+
+# Outlook add-in API requirement set 1.15
+
+The Outlook add-in API subset of the Office JavaScript API includes objects, methods, properties, and events that you can use in an Outlook add-in.
+
+## What's new in 1.15?
+
+Requirement set 1.15 includes all of the features of [requirement set 1.14](../requirement-set-1.14/outlook-requirement-set-1.14.md). It added the following features.
+
+- Added support for radio buttons to format reporting options in the [integrated spam-reporting](/office/dev/add-ins/outlook/spam-reporting) dialog.
+- Added support to include a "Don't show this message again" checkbox in a spam-reporting dialog that doesn't require input from a user.
+- Added support to open a task pane from a spam-reporting dialog.
+- Added support for Markdown to format error messages in a [Smart Alerts](/office/dev/add-ins/outlook/onmessagesend-onappointmentsend-events) dialog.
+- Added a method to load a single message from multiple selected messages to get its properties or perform operations on it.
+- Added an event that occurs when an add-in's task pane is opened from an [actionable message](/outlook/actionable-messages), [InsightMessage](/javascript/api/outlook/office.mailboxenums.itemnotificationmessagetype?view=outlook-js-1.15&preserve-view=true#fields) notification, Smart Alerts dialog, or an integrated spam-reporting dialog.
+- Added support for Base64-encoded attachments in reply forms.
+
+### Change log
+
+- Added the `inputType` attribute to the [ReportingOptions](/javascript/api/manifest/reportingoptions?view=outlook-js-1.15&preserve-view=true#attributes) element of the add-in only manifest: When implementing the integrated spam-reporting feature, uses radio buttons to format reporting options in the preprocessing dialog.
+- Added the [NeverShowAgainOption](/javascript/api/manifest/preprocessingdialog?view=outlook-js-1.15&preserve-view=true#child-elements) add-in only manifest element: When implementing the integrated spam-reporting feature, adds a "Don't show this message again" checkbox to the preprocessing dialog. This checkbox is supported in preprocessing dialogs that don't require input from a user.
+- Added new properties to [Office.SpamReportingEventCompletedOptions](/javascript/api/outlook/office.spamreportingeventcompletedoptions?view=outlook-js-1.15&preserve-view=true): Adds the following properties to configure a task pane to open from the **Report** button of the preprocessing dialog.
+  - [commandId](/javascript/api/outlook/office.spamreportingeventcompletedoptions?view=outlook-js-1.15&preserve-view=true#outlook-office-spamreportingeventcompletedoptions-commandid-member) property: When the **Report** option is selected from a preprocessing dialog, specifies the ID of the task pane that opens.
+  - [contextData](/javascript/api/outlook/office.spamreportingeventcompletedoptions?view=outlook-js-1.15&preserve-view=true#outlook-office-spamreportingeventcompletedoptions-contextdata-member) property: When the **Report** option is selected from a preprocessing dialog, specifies any JSON data passed to the add-in's task pane for processing.
+- Added the [errorMessageMarkdown](/javascript/api/outlook/office.smartalertseventcompletedoptions?view=outlook-js-1.15&preserve-view=true#outlook-office-smartalertseventcompletedoptions-errormessagemarkdown-member) property to [Office.SmartAlertsEventCompletedOptions](/javascript/api/outlook/office.smartalertseventcompletedoptions?view=outlook-js-1.15&preserve-view=true): Supports Markdown to format the error message shown in a Smart Alerts dialog.
+- Added the [Office.context.mailbox.loadItemByIdAsync](/javascript/api/outlook/office.mailbox?view=outlook-js-1.15&preserve-view=true#outlook-office-mailbox-loaditembyidasync-member(1)) method: When the [item multi-select](/office/dev/add-ins/outlook/item-multi-select) feature is implemented, loads a single item to perform operations on it or get properties that aren't provided by the [getSelectedItemsAsync](/javascript/api/outlook/office.mailbox?view=outlook-js-1.15&preserve-view=true#outlook-office-mailbox-getselecteditemsasync-member(1)) method.
+- Added the [Office.LoadedMessageCompose](/javascript/api/outlook/office.loadedmessagecompose?view=outlook-js-1.15&preserve-view=true) and [Office.LoadedMessageRead](/javascript/api/outlook/office.loadedmessageread?view=outlook-js-1.15&preserve-view=true) objects: Represents the properties and methods of a mail item that's currently loaded using the `loadItemByIdAsync` method.
+- Added the [Office.EventType.InitializationContextChanged](/javascript/api/office/office.eventtype?view=outlook-js-1.15&preserve-view=true#fields) event: Occurs when an add-in's task pane is opened from an actionable message, `InsightMessage` notification, Smart Alerts dialog, or integrated spam-reporting dialog.
+- Added [Office.InitializationContextChangedEventArgs](/javascript/api/outlook/office.initializationcontextchangedeventargs?view=outlook-js-1.15&preserve-view=true): When the `Office.EventType.InitializationContextChanged` event occurs, provides data from an actionable message, `InsightMessage` notification, Smart Alerts dialog, or integrated spam-reporting dialog to an add-in's task pane.
+- Updated the [type](/javascript/api/outlook/office.replyformattachment?view=outlook-js-1.15&preserve-view=true#outlook-office-replyformattachment-type-member) property of [Office.ReplyFormAttachment](/javascript/api/outlook/office.replyformattachment?view=outlook-js-1.15&preserve-view=true): Now supports Base64-encoded attachments in reply forms.
+- Added the [base64File](/javascript/api/outlook/office.replyformattachment?view=outlook-js-1.15&preserve-view=true#outlook-office-replyformattachment-base64file-member) property to `Office.ReplyFormAttachment`: Specifies the Base64-encoded string of the file to be attached to a reply form.
+- Added the [Office.MailboxEnums.AttachmentType.Base64](/javascript/api/outlook/office.mailboxenums.attachmenttype?view=outlook-js-1.15&preserve-view=true#fields) enum: Specifies that the attachment is a Base64-encoded file. This attachment type is only supported by the [displayReplyAllForm](office.context.mailbox.item.md#methods), [displayReplyAllFormAsync](office.context.mailbox.item.md#methods), [displayReplyForm](office.context.mailbox.item.md#methods), and [displayReplyFormAsync](office.context.mailbox.item.md#methods) methods.

+         * including the ability to send mail.
+         *
+         * The add-in should use the `restUrl` property to determine the correct URL to use when making REST API calls.

+
+
+      **Important**:
+
+
+      - In Outlook on the web, [new Outlook on
+      Windows](https://support.microsoft.com/office/656bb8d9-5a60-49b2-a98b-ba7822bc7627)<!-- -->, or classic Outlook on
+      Windows in online mode (non-cached mode), the item is saved to the server. In Outlook in cached mode, the item is
+      saved to the local cache.
+
+
+      - When working with HTML-formatted content, it's important to note that the Outlook client may modify the content.
+      This means that subsequent calls to methods like `Body.getAsync`<!-- -->, `Body.setAsync`<!-- -->, and even
+      `saveAsync` may not result in the same content.
+
+
+      - The identifier returned is the same as the [Exchange Web Services (EWS) item
+      identifier](https://learn.microsoft.com/exchange/client-developer/exchange-web-services/ews-identifiers-in-exchange)<!--
+      -->. The item ID returned isn't identical to the Outlook Entry ID or the ID used by the Outlook REST API. Before
+      making REST API calls using this value, it should be converted using `Office.context.mailbox.convertToRestId`<!--
+      -->.
+
+
+      - If your add-in calls `saveAsync` to get an item ID to use with EWS or the REST API, be aware that when Outlook
+      is in cached mode, it may take some time before the item is actually synced to the server. Until the item is
+      synced, using the item ID will return an error.
+
+
+      - In Outlook on Mac, only Version 16.35 (20030802) and later supports saving a meeting. Otherwise, the `saveAsync`
+      method fails when called from a meeting in compose mode. For a workaround, see [Cannot save a meeting as a draft
+      in Outlook for Mac by using Office JS
+      API](https://learn.microsoft.com/outlook/troubleshoot/calendars/cannot-save-meeting-as-draft-in-outlook-for-mac)<!--
+      -->.

+
+
+      - When working with HTML-formatted bodies, it's important to note that the client may modify the value passed to
+      `prependAsync` to make it render efficiently with its rendering engine. This means that the value returned from a

+      value that was passed in the previous `prependAsync` call.
+
+
+      - When including links in HTML markup, you can disable online link preview by setting the `id` attribute on the

+
+
+      **Important**:
+
+
+      - After the content is prepended, the position of the cursor depends on which client the add-in is running. In
+      Outlook on the web and on Windows
+      ([new](https://support.microsoft.com/office/656bb8d9-5a60-49b2-a98b-ba7822bc7627) and classic), the cursor
+      position remains the same in the preexisting content of the body. For example, if the cursor was positioned at the
+      beginning of the body prior to the `prependAsync` call, it will appear between the prepended content and the
+      preexisting content of the body after the call. In Outlook on Mac, the cursor position isn't preserved. The cursor
+      disappears after the `prependAsync` call and only reappears when the user selects something in the body of the
+      mail item.
+
+
+      - When working with HTML-formatted bodies, it's important to note that the client may modify the value passed to
+      `prependAsync` to make it render efficiently with its rendering engine. This means that the value returned from a
+      subsequent call to the `Body.getAsync` method (introduced in Mailbox 1.3) won't necessarily contain the exact
+      value that was passed in the previous `prependAsync` call.
+
+
+      - When including links in HTML markup, you can disable online link preview by setting the `id` attribute on the
+      anchor (<!-- -->&lt;<!-- -->a<!-- -->&gt;<!-- -->) to "LPNoLP" (see the **Examples** section for a sample).
+
+
+      - In Outlook on Android and on iOS, this method isn't supported in the Message Compose mode. Only the Appointment

+      - After the body is replaced with the specified content, the position of the cursor depends on which client the

+      item. In Outlook on the web and [new Outlook on
+      Windows](https://support.microsoft.com/office/656bb8d9-5a60-49b2-a98b-ba7822bc7627)<!-- -->, the cursor appears at

+      disappears after the `prependAsync` call and only reappears when the user selects something in the body of the
+      mail item.
+
+
+      - When working with HTML-formatted bodies, it's important to note that the value returned by the `Body.getAsync`
+      method won't necessarily be the exact same value that was previously passed in the `Body.setAsync` method. The
+      client may modify the value passed to `setAsync` to make it render efficiently with its rendering engine.
+
+
+      - When including links in HTML markup, you can disable online link preview by setting the `id` attribute on the
+      anchor (<!-- -->&lt;<!-- -->a<!-- -->&gt;<!-- -->) to "LPNoLP" (see the **Examples** section for a sample).
+
+
+      - In Outlook on Windows (classic) and on Mac, the add-in user isn't able to revert this action with the

+  **Important**: Entity-based contextual Outlook add-ins will be retired in Q2 of 2024. The work to retire this
+  feature will start in May and continue until the end of June. After June, contextual add-ins will no longer be able to
+  detect entities in mail items to perform tasks on them. The following APIs will also be retired.
+
+
+  - `Office.context.mailbox.item.getEntities` - `Office.context.mailbox.item.getEntitiesByType` -
+  `Office.context.mailbox.item.getFilteredEntitiesByName` - `Office.context.mailbox.item.getSelectedEntities`
+
+
+  To help minimize potential disruptions, the following will still be supported after entity-based contextual add-ins
+  are retired.
+
+
+  - An alternative implementation of the **Join Meeting** button, which is activated by online meeting add-ins, is
+  being developed. Once support for entity-based contextual add-ins ends, online meeting add-ins will automatically
+  transition to the alternative implementation to activate the **Join Meeting** button.
+
+
+  - Regular expression rules will continue to be supported after entity-based contextual add-ins are retired. We
+  recommend updating your contextual add-in to use regular expression rules as an alternative solution. For guidance on
+  how to implement these rules, see [Contextual Outlook
+  add-ins](https://learn.microsoft.com/office/dev/add-ins/outlook/contextual-outlook-add-ins)<!-- -->.

+uid: 'outlook!Office.Entities:interface'
+package: outlook!
+fullName: Office.Entities
+summary: >-
+  Represents a collection of entities found in an email message or appointment. Read mode only.
+
+
+  The `Entities` object is a container for the entity arrays returned by the `getEntities` and `getEntitiesByType`
+  methods when the item (either an email message or an appointment) contains one or more entities that have been found
+  by the server. You can use these entities in your code to provide additional context information to the viewer, such
+  as a map to an address found in the item, or to open a dialer for a phone number found in the item.
+
+
+  If no entities of the type specified in the property are present in the item, the property associated with that entity
+  is null. For example, if a message contains a street address and a phone number, the addresses property and
+  phoneNumbers property would contain information, and the other properties would be null.
+
+
+  To be recognized as an address, the string must contain a United States postal address that has at least a subset of
+  the elements of a street number, street name, city, state, and zip code.
+
+
+  To be recognized as a phone number, the string must contain a North American phone number format.
+
+
+  Entity recognition relies on natural language recognition that is based on machine learning of large amounts of data.
+  The recognition of an entity is non-deterministic and success sometimes relies on the particular context in the item.
+
+
+  When the property arrays are returned by the `getEntitiesByType` method, only the property for the specified entity
+  contains data; all other properties are null.

+  **Recommended practices**:
+
+
+  Currently, internet headers are a finite resource on a user's mailbox. When the quota is exhausted, you can't create
+  any more internet headers on that mailbox, which can result in unexpected behavior from clients that rely on this to
+  function.
+
+
+  Apply the following guidelines when you create internet headers in your add-in.
+
+
+  - Create the minimum number of headers required. The header quota is based on the total size of headers applied to a
+  message. In Exchange Online, the header limit is capped at 256 KB, while in an Exchange on-premises environment, the
+  limit is determined by your organization's administrator. For further information on header limits, see [Exchange
+  Online message
+  limits](https://learn.microsoft.com/office365/servicedescriptions/exchange-online-service-description/exchange-online-limits#message-limits)
+  and [Exchange Server message
+  limits](https://learn.microsoft.com/exchange/mail-flow/message-size-limits?view=exchserver-2019#types-of-message-size-limits)<!--
+  -->.
+
+
+  - Name headers so that you can reuse and update their values later. As such, avoid naming headers in a variable manner
+  (for example, based on user input or a timestamp).

+      This means that subsequent calls to methods like `Body.getAsync`<!-- -->, `Body.setAsync`<!-- -->, and even

+
+
+      - If your add-in calls `saveAsync` on an item in compose mode in order to get an item ID to use with EWS or the
+      REST API, be aware that when Outlook is in cached mode, it may take some time before the item is actually synced
+      to the server. Until the item is synced, using the item ID will return an error.
+
+
+      - In Outlook on the web and new Outlook on Windows, the mailbox account to which a draft is saved varies when
+      `saveAsync` is called on a message that will be sent from a shared mailbox account. If the sender creates a new
+      message from their personal mailbox and selects the shared mailbox account in the **From** field, `saveAsync`

+
+      **Important**:
+
+
+      - In Outlook on the web, [new Outlook on

+      Windows in online mode (non-cached mode), the item is saved to the server. In Outlook in cached mode, the item is
+      saved to the local cache.
+
+
+      - When working with HTML-formatted content, it's important to note that the Outlook client may modify the content.
+      This means that subsequent calls to methods like `Body.getAsync`<!-- -->, `Body.setAsync`<!-- -->, and even
+      `saveAsync` may not result in the same content.
+
+
+      - The identifier returned is the same as the [Exchange Web Services (EWS) item
+      identifier](https://learn.microsoft.com/exchange/client-developer/exchange-web-services/ews-identifiers-in-exchange)<!--
+      -->. The item ID returned isn't identical to the Outlook Entry ID or the ID used by the Outlook REST API. Before
+      making REST API calls using this value, it should be converted using `Office.context.mailbox.convertToRestId`<!--
+      -->.
+
+
+      - If your add-in calls `saveAsync` on an item in compose mode in order to get an item ID to use with EWS or the
+      REST API, be aware that when Outlook is in cached mode, it may take some time before the item is actually synced
+      to the server. Until the item is synced, using the item ID will return an error.
+
+
+      - In Outlook on the web and new Outlook on Windows, the mailbox account to which a draft is saved varies when
+      `saveAsync` is called on a message that will be sent from a shared mailbox account. If the sender creates a new
+      message from their personal mailbox and selects the shared mailbox account in the **From** field, `saveAsync`
+      saves the draft to the **Drafts** folder of the user's personal mailbox. If the sender opens the shared
+      mailbox account in a separate browser tab (through the **Open another mailbox** option, for example) and
+      creates a new message there, `saveAsync` saves the draft to the **Drafts** folder of the shared mailbox.

+
+
+      - The Outlook REST v2.0 and beta endpoints are now deprecated. However, privately released and AppSource-hosted
+      add-ins are able to use the REST service until extended support ends for Outlook 2019 on October 14, 2025. Traffic
+      from these add-ins is automatically identified for exemption. This exemption also applies to new add-ins developed
+      after March 31, 2024. Although add-ins are able to use the REST service until 2025, we highly encourage you to
+      migrate your add-ins to use [Microsoft
+      Graph](https://learn.microsoft.com/outlook/rest#outlook-rest-api-via-microsoft-graph)<!-- -->. For guidance, see
+      [Compare Microsoft Graph and Outlook REST API
+      endpoints](https://learn.microsoft.com/outlook/rest/compare-graph)<!-- -->.
+
+
+      - This method isn't supported if you load an add-in in an Outlook.com or Gmail mailbox.
+
+
+      - This method is only supported in read mode in Outlook on Android and on iOS. For more information on supported
+      APIs in Outlook mobile, see [Outlook JavaScript APIs supported in Outlook on mobile
+      devices](https://learn.microsoft.com/office/dev/add-ins/outlook/outlook-mobile-apis)<!-- -->.
+
+
+      - EWS operations aren't supported in add-ins running in Outlook on iOS and on Android. A REST token is always
+      returned in Outlook mobile clients even if `options.isRest` is set to `false`<!-- -->.
+
+
+      - Calling the `getCallbackTokenAsync` method in read mode requires a minimum permission level of **read
+      item**.
+
+
+      - Calling the `getCallbackTokenAsync` method in compose mode requires you to have saved the item. The `saveAsync`
+      method requires a minimum permission level of **read/write item**.
+
+

+
+
+      *REST Tokens*
+
+
+      When a REST token is requested (`options.isRest` = `true`<!-- -->), the resulting token won't work to authenticate
+      EWS calls. The token will be limited in scope to read-only access to the current item and its attachments, unless
+      the add-in has specified the **read/write mailbox** permission in its manifest. If the **read/write
+      mailbox** permission is specified, the resulting token will grant read/write access to mail, calendar, and
+      contacts, including the ability to send mail.
+
+
+      The add-in should use the `restUrl` property to determine the correct URL to use when making REST API calls.
+
+
+      This API works for the following scopes.
+
+
+      - `Mail.ReadWrite`
+
+
+      - `Mail.Send`
+
+
+      - `Calendars.ReadWrite`
+
+
+      - `Contacts.ReadWrite`
+
+
+      *EWS Tokens*
+
+
+      When an EWS token is requested (`options.isRest` = `false`<!-- -->), the resulting token won't work to
+      authenticate REST API calls. The token will be limited in scope to accessing the current item.
+
+
+      The add-in should use the `ewsUrl` property to determine the correct URL to use when making EWS calls.
+
+
+      You can pass both the token and either an attachment identifier or item identifier to an external system. That
+      system uses the token as a bearer authorization token to call the Exchange Web Services (EWS)
+      [GetAttachment](https://learn.microsoft.com/exchange/client-developer/web-service-reference/getattachment-operation)
+      operation or
+      [GetItem](https://learn.microsoft.com/exchange/client-developer/web-service-reference/getitem-operation) operation
+      to return an attachment or item. For example, you can create a remote service to [get attachments from the

+      -->, which gives organizations the tools needed to respond to the current threat landscape. Exchange user identity
+      tokens will still work for Exchange on-premises. Nested app authentication (NAA) is the recommended approach for

+
+
+      - To enable the `makeEwsRequestAsync` method to make EWS requests, the server administrator must set
+      `OAuthAuthentication` to `true` on the Client Access Server EWS directory .
+
+
+      - Your add-in must have the **read/write mailbox** permission to use the `makeEwsRequestAsync` method. For
+      information about using the **read/write mailbox** permission and the EWS operations that you can call with
+      the `makeEwsRequestAsync` method, see [Specify permissions for mail add-in access to the user's
+      mailbox](https://learn.microsoft.com/office/dev/add-ins/outlook/understanding-outlook-add-in-permissions)<!-- -->.
+
+
+      - If your add-in needs to access Folder Associated Items or its XML request must specify UTF-8 encoding (`\<?xml
+      version="1.0" encoding="utf-8"?\>`<!-- -->), it must use Microsoft Graph or REST APIs to access the user's mailbox
+      instead.
+
+
+      - This method isn't supported in Outlook on Android or on iOS. For more information on supported APIs in Outlook
+      mobile, see [Outlook JavaScript APIs supported in Outlook on mobile
+      devices](https://learn.microsoft.com/office/dev/add-ins/outlook/outlook-mobile-apis)<!-- -->.
+
+
+      - This method isn't supported when the add-in is loaded in a Gmail mailbox.
+
+
+      - When you use the `makeEwsRequestAsync` method in add-ins that run in Outlook versions earlier than Version
+      15.0.4535.1004, you must set the encoding value to ISO-8859-1 (`<?xml version="1.0" encoding="iso-8859-1"?>`<!--
+      -->). To determine the version of an Outlook client, use the `mailbox.diagnostics.hostVersion` property. You don't
+      need to set the encoding value when your add-in is running in Outlook on the web or [new Outlook on
+      Windows](https://support.microsoft.com/office/656bb8d9-5a60-49b2-a98b-ba7822bc7627)<!-- -->. To determine the
+      Outlook client in which your add-in is running, use the `mailbox.diagnostics.hostName` property.

+      In classic Outlook on Windows, the appointment organizer is included in the object returned by the `getAsync`
+      method when you create a new appointment or edit an existing one. In Outlook on the web and new Outlook on
+      Windows, the organizer is only included in the returned object when you edit an existing appointment.
+
+
+      The `getAsync` method only returns recipients resolved by the Outlook client. A resolved recipient has the
+      following characteristics.
+
+
+      - If the recipient has a saved entry in the sender's address book, Outlook resolves the email address to the
+      recipient's saved display name.
+
+
+      - A Teams meeting status icon appears before the recipient's name or email address.
+
+
+      - A semicolon appears after the recipient's name or email address.
+
+
+      - The recipient's name or email address is underlined or enclosed in a box.
+
+
+      To resolve an email address once it's added to a mail item, the sender must use the **Tab** key or select a
+      suggested contact or email address from the auto-complete list.
+
+
+      In Outlook on the web and on Windows (new and classic), if a user creates a new message by activating a contact's
+      email address link from their contact or profile card, your add-in's `Recipients.getAsync` call returns the
+      contact's email address in the `displayName` property of the associated
+      [EmailAddressDetails](xref:outlook!Office.EmailAddressDetails:interface) object instead of the contact's saved

+summary: >-
+  The settings created by using the methods of the `RoamingSettings` object are saved per add-in and per user. That is,
+  they are available only to the add-in that created them, and only from the user's mailbox in which they are saved.
+
+
+  While the Outlook add-in API limits access to these settings to only the add-in that created them, these settings
+  shouldn't be considered secure storage. They can be accessed by Exchange Web Services or Extended MAPI. They shouldn't
+  be used to store sensitive information, such as user credentials or security tokens.
+
+
+  The name of a setting is a String, while the value can be a String, Number, Boolean, null, Object, or Array.
+
+
+  The `RoamingSettings` object is accessible via the `roamingSettings` property in the `Office.context` namespace.
+
+
+  To learn more about `RoamingSettings`<!-- -->, see [Get and set add-in metadata for an Outlook
+  add-in](https://learn.microsoft.com/office/dev/add-ins/outlook/metadata-for-an-outlook-add-in)<!-- -->.
+remarks: >-
+  \[ [API set: Mailbox 1.1](/javascript/api/requirement-sets/outlook/outlook-api-requirement-sets) \]
+
+
+  **Important**:
+
+
+  - The `RoamingSettings` object is initialized from the persisted storage only when the add-in is first loaded. For
+  task panes, this means that it's only initialized when the task pane first opens. If the task pane navigates to
+  another page or reloads the current page, the in-memory object is reset to its initial values, even if your add-in has
+  persisted changes. The persisted changes will not be available until the task pane (or item in the case of UI-less
+  add-ins) is closed and reopened.
+
+
+  - When set and saved through Outlook on Windows
+  ([new](https://support.microsoft.com/office/656bb8d9-5a60-49b2-a98b-ba7822bc7627) or classic) or on Mac, these
+  settings are reflected in Outlook on the web only after a browser refresh.
