We're testing an Exchange 2013 DAG setup. 3 total multi-role servers, configured via MS Best Practices. Production NIC and Replication NIC for all DAG traffic.
The issue we're running into, is every night, the mailbox databases Activate on Server 3. Each morning, we rebalance them. 1 mailbox database on Server 1, 1 mailbox database on Server 2 and 1 mailbox database on Server 3.
I come in the next day, all 3 databases are Active on Server 3.
I'm scanning the Event logs, however, there are thousand generated over night.
I'm hoping someone can point me in the right direction. Does Exchange automatically balance them?
