As you might imagine, lots of calls and questions about DST issues are coming in across many different products. There are a couple of field notices that may be helpful if you?re having problems.

For Unity Connection, start here:

Unity 4.21 - failover pair with exchange message store server as DC.

I applied the patches to the servers earlier this week...the following occurred after 2am Sunday:

Time on the message store server was ok

Time on the primary and failover was not changed.

When time was manually set on the servers, the Primary and Failover would go out of sync by 1 hour repeatedly.

I stopped the unity services on the Failover server, rebooted and waited for time sync with the DC. I then started failover mode and then did the same to the Primary. After few hours with no time problems I failed back to the Primary.

I had no issue with single server sites. I suspect this had to do with the SQL replication.

P.S.

I did not change the check on the auto DST checkbox, it was on in all servers.

I would like to know what will occur in November: I anticipate I will have to manually change time on the Exchange box and reboot the Unity servers, and forget about automatic DST changes.

This could be the following microsoft bug posted in the earlier thread:
