We installed an Exchange 2010 server (MB role only) in our native Exchange 2007 environment to kick the tires. We're done kicking now, but i'm concerned that uninstalling Exchange 2010 could be problematic. For instance, when i run the uninstall it says that there's still arbitration mailboxes that have to be removed or disabled first. I read up on arbitration mailboxes and it seems that deleting them can cause problems.
We're going to migrate to Exchange 2010 at some point, but will removing this existing installation cause problems with our current setup and/or our ability to start adding new Exchange 2010 servers down the road? If it's safe to remove it, are there any recommendations on what to do with the arbitration mailboxes?
Thanks in advance!
