With Exchange 2003 end-of-life deadline looming ever closer I thought it would be a good time to revisit the syntax for upgrading the Recipient Update Policies in Exchange 2003 to the Email Address Policies in Exchange 2010.
If you have received the error below when you try to double-click or edit an Email Address Policy in the Exchange Management Console, then your Recipient Update Policy still needs to be updated.
The specified e-mail address policy couldn't be edited. E-mail address policies created with legacy versions of Exchange must be upgraded using the 'Set-EmailAddressPolicy' task, with the Exchange 2010 Recipient Filter specified.
To update the Email Address Policy open Exchange Management Shell and issue the command below. This command finds all the current legacy Email Address Policies (Recipient Update Policies from Exchange 2003) and pipes those findings directly into the Set-EmailAddressPolicy cmdlet. This cmdlet converts those Recipient Update Policies into Email Address Policies. You will be prompted to confirm.
