Users receive "Welcome to Unified Messaging email" messages in Office 365 Dedicated/ITAR

Symptoms
In a Microsoft Office 365 Dedicated/ITAR environment, users receive an email message that states "Welcome to Unified Messaging." 
Cause
This issue occurs if one or more for the following conditions are true:
  • The user is moved from the dedicated forest to a Unified Messaging (UM)–enabled mailbox. 
  • The user wasn't moved to the service recently but resides on the service for a period of time. In this situation, they continue to receive "Welcome to UM" messages.  
Resolution
This is the expected behavior after a user's move to the service is completed.

In any other situation where a user receives this message, escalate the incident to Microsoft Support. This is part of a known issue in which mailboxes that experience load balancing moves may receive the "Welcome to UM" message again. When you escalate, make sure that you include the following information:
  • The move history for the mailbox. To do this, run the following cmdlet:

    Get-MailboxStatistics <mailbox> -IncludeMoveHistory | fl *move*
  • Message tracking that shows the message being delivered to the mailbox. You can do this either from remote PowerShell or EAC.
