I have recently done a migration to 365 and I have an in house Exchange 2010 server. As I expected there are people who are still connected to the old server even though there has been numerous emails regarding the update. I really wish I could shut down the Exchange server, so users with outdated setting will get bumped and we can ID them that way, but I have an inventory software running on that same server, so I can not physically turn it off.
What is the best way to stop the Exchange 2010 (ONLY) from running and responding without shutting it down.
Thanks
