You can't upgrade Windows when Exchange is installed on the server.

I figured I’d give it a go anyway. I mean, like, what’s the worse that could happen, right? A quick Hyper-V Checkpoint (snapshot) created, checked last nights backups were good and away we go! After the upgrade, the worst happened 😦 (more…)
