We are currently on Exch 2007 migrated from Exch 2003. Prior to Exchange the company had GW for it email system. The email address policy includes and entry for migrate.hernandocounty.us. Everytime I create a new mailbox for a user, not only does the user get our new domain but also the "migrate" one too. I have tried to remove it from the policy but receive the following error. Summary: 2 item(s). 0 succeeded, 1 failed. Elapsed time: 00:00:01 Edit Default Policy Failed Error: The e-mail address policy object "Default Policy" is invalid because it contains invalid e-mail address templates: 'GWISE:Exchange.First Administrative Group.&m'. 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: 00:00:01 Apply Default Policy Cancelled

Edit your E-mail Address Policy and remove the GWISE address. You can use Get-EmailAddressPolicy and Set-EmailAddressPolicy cmdlets in PowerShell to do this, or you should be able to change it in the Console. Here's one reference: http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/managing-email-address-policies.html There are plenty more.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

I made the changes using Adsiedit.msc for the Disabled Gateway proxy and created a test user mailbox. It still added the migrate address.
