I've got some mailboxes with wrong email addresses. I've corrected the AD account, but the old one is still being recognized in Exchange. How do I correct wrong email address?

Sounds like you have a routing recipiant policy not doing what you think it should be doing. What is wrong with the email address? User part of domain part? Do you have corresponding recipiant polices for each? It might need to sync since you made the change. Have you forced syncroniation between DC's and GC's since you made the change? Thanks

The user part is wrong the domain is correct and no I have not forced syncronization..

Try force syncing the domain controllers. You might have changed it on one DC.... and it has not rolled to the one exchange is using yet. How long has it been since you changed it?

This is a brand new email system, from scratch and I've found 20 or accounts that had the wrong email address in their AD account properties. I just finishedcross checking the Exchange MailboxEmail accounts with what's in ADand I corrected all of the AD accounts last week, but the wrong email address is still in the Exchange mailbox. I just went to properties on some of the mailboxex and went to the Email Address taband added the correct address as an SMTP email address and then tried to delete the wrong one. I can't delete the wrong one until I promote the new one. I can't find anything on promoting an SMTP email address. Long answer for a short question.I made the corrections in AD last week.

Just set the new one as the reply to address and then delete the old one. Set the new "correct"email addressas the primary reply to address by clicking the new corrected email adress and then clicking the bottom right button "set as primary" Then you can delete the old one. This is assuming the system is Exchange 2003? Also the email adddress might be resetting itself because of an policy that is being run periodically. Uncheck the box that says "automatically update etc...." on the same tab so thepolicy will not impact these users. Or correct the policy either one. If it is a 2007 system do this from the 2007 exchange management console for 2007. the difference is that it called "set as reply" instead of "set as primary". Hope this helps.

That did it, I wasn't unchecking the "automatically update...." box. Once I unchecked that and made the new email address the main reply to, then I could delete the wrong one and now Exchange matches AD. This is 2007. Thanks..
