Hi,

I have a 2node Exchange DAG on 2013 SP1, all is fine however quite often 2 of my mailbox DBs flip over to server 2, always the same pattern.  What's the best way to determine the reason why?

DB1 & DB2 sit on Exchange 1 for a while and then eventually move over, I checked logs but impossible to track!
