Can't use -On or -After in simple scripts on diff versions

[AliRazeghi]

I tried this on Powershell 2 and Powershell 4 on Windows Server 2008 and Windows 7 using different PCs.

This is a sample code:
$EmailUser = 'Test@GMail.Com'
$EmailUser2 = 'Test@Test.Com'
$EmailSubject = "isAlive"
$pw = [System.Convert]::FromBase64String("Base64Password")
$pw = [System.Text.Encoding]::UTF8.GetString($pw)

$secpasswd = ConvertTo-SecureString $pw -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($EmailUser, $secpasswd)
$gmail = New-GmailSession -Credential $mycreds

$inbox = $gmail | Get-Mailbox
$inbox | Get-Message -Before "2014-11-30" ## This works fine.
$inbox | Get-Message -After "2014-11-30" ## This does not work.

Using -After gives us this error:

"Exception calling "Search" with "1" argument(s): "xm003 BAD Could not parse command"
At C:\Windows\system32\WindowsPowerShell\v1.0\Modules\Gmail.ps\Gmail.ps.psm1:344 char:5

• $result = $Session.Search('(' + $criteria + ')');

Using -On gives us this error:

It appears you have found the problem.
Cannot process argument transformation on parameter 'date'. Cannot convert null to type "System.DateTime"
On line 275 of Gmail.ps\Gmail.ps.psm1
if ($On) {
$imap += 'ON "' + $(GetRFC2060Date $After) + '"'
}
Notice that $After is passed instead of $On
This needs to be corrected.
