Service restart has forced the mailbox instances to start failing over. We should have services fully recovered for all users shortly.

We are experiencing a minor outage affecting 84 mailboxes on our Exchange 2016 platform. Our teams are trying to determine why the failover did not occur correctly, and out of abundance of caution, we aren't terminating the system call.

In the meantime, all 84 users affected by this Exchange database outage can still send and receive email at while the maintenance is underway.
