Exchange 2010 upgrade to SP1 - Fails on Prerequisites.
I'm getting this weird error, and there is nothing on the internet I can find to help.
When I try to upgrade to SP1 I get this error.
Setup cannot continue with the upgrade because the resource property contains invalid data: The object is read-only because it was created in a version of Exchange later than Exchange 0.10 (188.8.131.52). Current supported version is 0.1 (8.0.535.0).
Click here for help... and you've guessed it when I click the link, there isn't a page about this error yet!!!?!?!
Has anyone come across this issue before, or can anyone point me in the direction of fixing this?????
Thanks all in advance!
