Hi,
I have a couple of exchange 2010 servers that need pathing. I just took over the systems in this company and exchange has not been patched for a long time so there are like 70 patches. I guess i'd patch 10 and 10 patches to reduce the risk of some failures after reboot. Normally i use snapshots of VMs to safeguard against errors after patching, but is it supported to snapshot an exchange server in that respect - i.e. snapshot - patch - if error = rollback snapshot or would rolling back the snapshot screw up my exchange/AD?
