Most over the range microwaves can be rear vented. The user manual and or installation guide should reference this.
I did not have the installation guide but now I have found a copy at Google and have downloaded it. Yes it can be vented from the back with a standard rectangular duct. Now that I know it is feasible, I can now get someone to help me install a rear exhaust.
