I must admit I was under the impression that it should be possible to activate a passive database copy seemlessly with no issue for users. Unfortunately, that does not appear to be the case. Outlook loses connection temporarily.
Not for long - probably 30 seconds but enough to get plenty of moaning from users if done during the daytime.
Is this normal? Obviously, there is sometimes a need to switch activity like this from one DAG server to another. For instance, at the moment, I'm performing CU11 upgrade so need to move active mailboxes off etc. With 32 mailbox database rapidly filling up with user mailboxes as we migrate its going to be nigh on impossible to switch during normal hours at the moment.
But, is this the expected results or not?
