Exchange 2010 Removal from Domain
I completed a migration to Office 365 a few weeks back and am now ready to remove the previous Exchange 2010 environment from my local domain.
Single Exchange 2010 Server, fairly small environment. I know that essentially the step is to simply run Add/Remove Programs, however do I need to remove all of the mailboxes or take any other steps before that uninstall will complete successfully?

don't do what I did!!!
don't remove the users in the EMC....it will delete active directory users as well in the process. it will tell you it deletes the object before you click OK but it's not enough of a warning....

i just finished my migration here where we had exchange and we had already migrated mail to another host so exchange was no longer needed. after the migration we didnt even demote the old one, we just ran a metadata clean up and removed all of the old server from dns. things are running great
If you've done the dirsync with 365 and have migrated all mailboxes over, see EE comments at https://www.experts-exchange.com/questions/28555338/Remove-last-exchange-2010-server-after-migration-to-office-365.html
