I have what I think is a quick easy question. I'd like to apply a service pack to my exchange 2007 mailbox server. I don't have a CCR setup, so its a pretty standard configuration. We do have it running on VMware and I plan on snapshotting it before the service pack is applied.
My question is, can certain aspects of exchange be disabled so that outlook can't connect to the mailbox server before I snapshot/update the server? I'd like to avoid any data loss if it can be done. For example, one idea I had was disabling the mailbox databases and then patching the server. However, I don't know if that can be done.
Another idea I had was patching the exchange server while the network is disconnected, but once again, I don't know if that would work either.
