I updated my 2010 Exchange to SP3. The server is a VM so I took a snapshot before hand. The install failed (sorry I dont have error message ) and after reboot Exchange was not functioning correctly. I reverted back to the snap shot before the SP3 and everything came back up.
This is where it gets strange. I have since tried to update SP and I get error messages stating this update does not apply.
When I look under installed updates it only shows RU 5 for SP1.
EMC shows 14.3(Build 123.4)
Exsetup.exe details shows 14.0.726.0
It appears that I actually have SP1 RU 5 but Exchange thinks I have SP3. I can also tell I dont have a new SP because I am missing the newer powershell cmds that came with later SPs.
I need to get this Exchange server updated so please help!
