Exchange 2007

We've been working on a big Exchange 2007 migration project and I thought I'd share some of the lesser mentioned hurdles we seemed to hit:

We are using virtual servers under ESX vi3, and found we were getting daily stop errors until a colleague found this VMware kb article. We only had one other virtual 64 bit box at that point, and it did not yet have the 932596 patch so we were a bit stumped until we found the VMware KB.

We also had an issue (before even moving the Offline address book generation) where the 2007 install broke OAB 2 and 3a generation. A Microsoft escalation engineer (the cool guy who wrote the oabInteg tool) blogged about it here.

We also had issues (also before moving our recipient polices to 2007) with our recipient polices not updating because we needed to remove some disabledGateway Proxy entries. The official Microsoft KB is 948211, but I found a blog entry from Dusan Kosaric to be what turned me on to the problem.

Lastly, I wanted to exclude certain domain controllers from being used by Exchange 2007 (as opposed as to just hard coding what dc's to use) and used KB 298879.
