The user does not have a mailbox (or e-mail Active Directory attributes are missing).

We are getting the following error message with all users from within the rule deployment wizard for CRM 2011 RU7 with exchange 2010 sp1.

Error: The user does not have a mailbox (or e-mail Active Directory attributes are missing).  

We are getting no errors in the router itself. We have the forwarding mailbox configured with a domain user that has Exchange Organization Administrator permissions and is a user with a base security role in CRM.

The incoming profile is setup with the logon credentials of this same user.

Any assistance would be greatly appreciated.
