Determing if there any live users left on Exchange 2007
Posted on 2016-08-31
Got a co-located system with both 2007 and 2013. We've migrated nearly everyone we wanted to 2013 now.
BUT, we didn't want to migrate old users or disabled users. However, it appears our plan wasn't that good.
Is there any way to tell (from message tracking logs maybe) whether there are any users out there who are still on Exchange 2007 and using this to send email?
