Hi, I am running on Windows 2003 Servers for AD and Exchange 2003 . Last few weeks I noticed for few users, a strange email id got created automatically, and it made itself as the Primary ID (eg. mike.mikemike@mydomain.com) the actual address should be mike@mydomain.com , I am the only administrator who can create the user ID's. While this address gets created, any of the affected users send email outside and in the meantime I remove the fake address, the reply gets bounced. All my updates are current, Anti virus is current. Any advice, Cheers, Mittapalli
