Hi

we need some help getting rid of an Exchange 2013 virtual server from the domain which also has a 2010 exchange server (also a VM). The 2013 one went on first but for one reason or another didn't take so we had to put on the 2010. Now we've found we can't just get rid of the 2013 because of issues with the OAB.

Is there any way to move the OAB back to the 2010 so we can remove the 2013 as it is taking up valuable resources and is pretty much redundant?

You need to create an OAB on the Exchange 2010 server, and then set it as the default OAB on all of the Exchange 2010 databases.
Then you can remove the Exchange 2013 OAB and the uninstall should go through correctly.

The OAB doesn't move between Exchange 2010 and 2013, they are completely different.

Simon.
