Custom script modules running against Microsoft Exchange in onPostCreate handler are executing without error but no operation is performed -
Descrizione
In a custom Active Roles Script Module, cmdlets which are executed against Microsoft Exchange in an onPostCreate handler do not throw an error message, but no operation is completed in Microsoft Exchange.
For example, the following script module could be used in an attempt to set the "AuditEnabled" for new mailbox users:
function onPostCreate($Request)
{Add-PSSnapin Microsoft.Exchange.Management.PowerShell.*$UserSamAccountName = $DirObj.Get("samAccountName")Set-Mailbox -Identity $UserSamAccountName -AuditEnabled $true}Active Roles Verbose logging and Script Logging will show these commands executing without error, but this flag will not be set on the mailbox when in Microsoft Exchange. -
Causa
This is expected in larger environments due to a Race Condition with Microsoft Exchange mailbox creation. -
Risoluzione
The onPostCreate handler is triggered after a User's Active Directory User Account is created. The Microsoft Exchange PowerShell is being sent and processed before this User's Microsoft Exchange mailbox exists.
This can be best handled by spawning a PowerShell Job or a PowerShell Runspace.
Have the job or runspace run a Sleep cmdlet and periodically check to see if Get-Mailbox returns a result. Once it does, send the desired cmdlets.
