The email address of a user is updated unexpectedly after you run the Update-Recipient cmdlet on an Exchange Server 2010 server


Symptoms


Consider the following scenario:
  • You have the email address of a user whose account is hosted on a computer that is running Microsoft Exchange Server 2010.
  • You run the following cmdlet on the Exchange Server 2010 server:
    Set-Mailbox - Identity <user name> -EmailAddressPolicyEnabled $False
  • The msExchPoliciesExcluded property of the user is set to the GUID of the default email address policy and the msExchPoliciesIncluded property of the user is set to null.
  • You run the following cmdlet on the Exchange Server 2010 server:
    Update-Recipient - Identity <user name>

In this scenario, the msExchPoliciesIncluded property of the user is incorrectly set to the GUID of the default email address policy. Therefore, the email address of the user is updated unexpectedly.

Note This problem does not occur in Exchange Server 2007 environments.
