Exchange 2007 does not automatically update address lists, global address lists, or user objects subject to an email address policy. In Exchange 2003, recipient update services used to take care of this, but this services is not present in Exchange 2007. Now, you must use scheduled powershell commands to update address lists if they are build upon object attributes that can change from time to time. For example, the address lists of one of our customers are build to key on the "office location" user object attribute. However, if the attribute is changed, Exchange does not automatically recalculate the address list membership. The following scripts are a good way to keep them updated by scheduling them with the Window's scheduler:
- Get-AddressList | Update-AddressList
- Get-EmailAddressPolicy | Update-EmailAddressPolicy
