I have also restarted the services/ server a couple of times.The exchange 2007 runs on a Win 2k3 64 bit edition and is not part of a cluster.Besides there is an instance (System Manager) of Exchange 2003 installed on a server - however,thisand the stores areno longer in use.Summary: 1 item(s). 0 succeeded, 1 failed. Elapsed time: 00:00:00 A UserFailed Error:A proxy generator DLL on server mail.server.com could not be found or failed to initialize. Proxy addresses for the current recipient cannot be calculated.

Have you seen below? Error message when you create a mailbox on a second or successive clustered mailbox server of an Exchange Server 2007 Single Copy Cluster: "A proxy generator DLL on server <FQDN.serverName> could not be found or failed to initialize" http://support.microsoft.com/kb/928811Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Thanks. I have already been through the article and made the necessary amendments. However, the issue persists

Check your Email Address Policies. per:http://technet.microsoft.com/en-us/library/bb124401.aspxAny that do not conform? When did this start?

I have a default email policy in exchange 2007. But when i click to edit and just run through, it gives the following error:Edit Default PolicyFailed Error:The e-mail address policy object "Default Policy" is invalid because it contains invalid e-mail address templates: 'smtp:%g.%s@domain.com, 'X400:c=GB;a= ;p=DOMAIN;o=Exchange;'. To view details of the error, see the application event log in the Windows Event Viewer on the Microsoft Exchange Server computer. Exchange Management Shell command attempted:set-EmailAddressPolicy -Instance 'Default Policy' Elapsed Time: 00:00:00 Apply Default PolicyCancelled

What are the details in the app log? Can you post what you get with:Get-EmailAddressPolicy | fl

And nothing in the app log?What was changed on: 24/11/2009 19:23:35

I rebooted the servers yesterday, and noticed the mail policy was not enabled.Therefore I enabled it to ascertain if it was that, which was causing the issueI can't see anythng obvious in the event viewer

I used ADSIEDIT.MSC and deleted the proxyAddresses attributes in CN=default policies. This aloowed me to create a mailbox. I then added the email addresses manually

Glad you got it working!

Hi, I'm having the same problem. How did you do the change in the ADSIEDIT.MSC? Angel acorona@cyamexico.com
