I recently did a migration from Exchange 2003 to 2010. Everything seems to be working. After having the 2003 server shut down for a week or two with no issues, I decided to uninstall it.
After a few issues with remaining mailboxes etc, the uninstall process via Add/Removed ran. I had one error during the uninstall but unfortunately I didn't write it down. I believe it said something the effect of an error with messaging or something.
After click past that, the uninstall proceeded. If I now go into Add/Remove, the option for MS Exchange is no longer there however some of the services are still on the server, specifically the System Attendant and Exchange Management and they were running.
I have stopped and disable all Exchange services.
So my question is - how can I be sure it has uninstalled correctly and what are the ramifications if it didn't? Everything seems to be working but I just have this feeling that something is still left out there and things weren't completely cleaned up.
Thank you for your help.
