I have SBS2011 where Exchange Server Active Sync fails and I can't fix the problem.
It sends and receives email just fine except:
(1) it fails to run Exchange Management Shell
(2) Active Sync as far as synching email/contact/calendar on smartphone fails
(3) can't run https://remote.domain.com/remote or /owa.
I spent a lot of time on this board to fix the problem, but to no avail.
So I am thinking about restoring OS to the date when all was working fine.
I have been doing Windows Server Backup every day and like to know if I can restore the system (by picking the right date when all was working fine) without restoring exchange data or user document & files.
