I recently started to administer an Exchange 2007 server that was (partially) migrated from Exchange 2003. The migration was from one physical server to another and the source server is still running at the moment. Since the beginning I always been able to create new user's mailbox without any issue but this morning I receive the following error:
A proxy generator DLL on server *SERVERNAME* could not be found or failed to initialize. Proxy addresses for the current recipient cannot be calculated. Please ensure that all the proxy address generator DLLs have been installed on the target server.
This error occurs if I create the user first in AD and then try to link to a new mailbox or if I do everything from EMC. Although I tried the resolution from this KB (http://support.microsoft.com/kb/928811
) it doesn't have anything to do with my problem.
I ran the Best Practice Analyzer tool but it didn't find anything of value.
One thing worth mentioning is that I also tried to play with the default address policy which is marked as applied but if I try to edit it (even while making no changes at all) return the error:
The e-mail address policy object "Default Policy" is invalid because it contains invalid e-mail address templates: 'SMTP:@domain.com'. To view details of the error, see the application event log in the Windows Event Viewer on the Microsoft Exchange Server computer.
I checked the event log and nothing show up there.
Finally, I know that somebody else played with the active directory, creating OUs and moving users around. Maybe it has something to do with OUs security?
