Thanks. Yes the old server has been decommissioned. Besides these 2 users there are exchange objects, I'll have to check the other items/accounts. They stopped using exchange months ago but I had just disabled all services and didn't uninstall that's why those show up.

Did you uninstall from the 2003 server before you switched it off? If the plan wasn't to use Exchange in the new 2012 environment then it would have been better to uninstall Exchange otherwise you will have issues if you ever plan to redeploy Exchange again.

<div>
I should've been specific, this is Essentials 2012 R2 so they will not be installing Exchange on it.

OK fair enough. I still would have personally gracefully removed Exchange from the environment in case of any weird lingering issues that may arise down the track. Let me know if you need any info on other accounts that you'd like to remove.

I've removed the Exchange objects and other accounts after disabling them for a period, thanks.

I've finished 2003 to 2012 migration, all working fine. The migration moved over some user accounts such as Iuser_server and &nbsp;Iwam_server. I am assuming these can be deleted, they are marked as active (not by me).<br />
<br />
There are some other objects in AD computers and users that were part of the old 2003 when we had Trend Micro, can these also be removed?Is there some easy way to clean up all this old stuff?
