I am running Exchange 2003 on Server 2003 SBS. We have about 10 users. Two of these users are experiencing an issue where their e-mail address property in AD is somehow reverting back to their account name. Here's what I mean:
If their main account name is JoeSmith, and I want to change their e-mail to just firstname.lastname@example.org, I go into their exchange e-mail addresses and change their primary smtp account to email@example.com, right? The problem is that it changes that SMTP account back to JoeSmith@domain.com. I go in and manually change it to firstname.lastname@example.org, wait about 2 minutes, go back in and check the address and POOF. it changes it back to whatever the default account name in AD is. Why does this happen? And how can I change it? Since the e-mail address it's reverting back to isn't really their REAL e-mail address that everyone has, they aren't getting mail at the e-mail address everyone is sending to.
If this sounded too confusing just as me questions to clarify. Thank you in advance!
