Exchange 2010 remove from domain and rejoin

We have an issue with a Windows 2008 R2 box which has Exchange 2010 SP1. BES is also connected to the Exchange server. Microsoft has made a recommendation that we need to disconnect the Exchange server from the domain and reconnect it afterwards. We are using vSphere/ESX 4, so I can create snapshots of our DC's, Exchange and BES server beforehand and revert back if needed. Do you see any problems with disconnecting from the domain and rejoining? Thank you.

Ive done this within my own environment to recreate a trust.

Exchange refers to the domain so as long as you reconnect it to the same domain you should have no issues with this

I was able to disconnect from the domain and reconnect. There were 2 problems that needed to be fixed first. After rejoining I needed to make the server a member of the following Groups in AD:
Domain Computers
Exchange Enterprise Servers
Exchange Install Domain Servers
Exchange Servers
Exchange Trusted Subsystem

I then needed to delete the user profile on the Exchange server that it was using before the disconnect. Then I logged back in using the same credentials to recreate the profile.
Everything was fine after that.
