Our Active Exchange server (cluster of two 2013 Exchange servers running on 2012R2) suddenly issued an error re. unified messaging at 6:40 this morning.

When I connected server was still up (ping and sign in no problem) with Unified Messaging service down and would not start.

Lot’s of 1038 and 1430 events

Seemed to be the only service down and no errors or issues on passive server. However, it stopped webmail, outlook and MDM email on iphone

Active server also had issues accessing a DC in the domain. Passive server and all others (file server, application server, etc.) are all fine. Both DC (2016) up and running entire time.

However, a reboot of the server fixed it for now and all is normal again without further errors.

 

I note that we recently (past two weeks) had to renew certificates and read that issues with that can cause these events. Has anyone experienced this.

Many thanks in advance.

Did you recycle the UM service after changing certificates? Exchange UM will not use the new one until this is done, so if the old certificate expired overnight that might have been your problem.
