We have Exchange 2003 and are going to Office 365. &nbsp;Running the Hybrid Configuration I receive the following error: during validation in agent 'Rus Agent': 'Failed to validate the proxy address template &quot;MRS:@MRS&quot;. Additional information: Failed to find the address type object in Active Directory for address type &quot;MRS:AMD64&quot;.. '<br />
<br />
In Exchange 2003 I have UM integration with voicemail so everyone has username@mrs for the voicemail server to forward messages to the users Outlook. &nbsp;Everything I read says to remove this from the policy but I'm afraid if I do it will remove all users username@mrs from their ADUC account and stop delivering voicemail.
