I have an exchange server 2013 DAG install at my workplace.
I have 2 CAS server and 2 Mailbox server.
there is 14 DB
MBX1 was always the preferred active server for the 14 DB but for a reason that i don't understand is that the 14 DB are now balance between MBX1 and MBX2 meaning 7 DB on MBX1 and 7 DB on MBX2.
MBX1 is the active preference with a value of 1 and MBX2 is with a value of 2. What could be the issue. The mail server works and I saw that it is best practice to keep everything in balance with the DB,
This just happen two weeks ago for no reason.
How can we explain that behavior.
