So, I was at a customer uninstalling an Exchange 2013 server as the customer had finished their migration to Office 365.
Went through the usual process of decommissioning the server, such as ensuring no mailboxes where left, removing arbitration boxes and so on.
Got to the point where the actual uninstall could take place, and was faced with this:
Thought to myself, that was kinda weird… Looking in Task Manager showed that ESEUTIL has a lot of processes running:
Well, since all data had been migrated away from the server and all databases had been removed I didn’t see much point in finding out why all these ESEUTIL processes where spawned.
A simple reboot later, and the uninstall procedure continued without any problems.
