So, you have updated your SSL certificates in Exchange 2010 to comply with (insert corporate policy here). All seems well until you receive a frantic call: “Voice Mail is down!”.
A quick search of the event viewer turns up:
The Microsoft Exchange Unified Messaging service was unable to start. More information: “Microsoft.Exchange.UM.UMService.UMServiceException: No certificate was found using the thumbprint ” specified in the UMCertificateThumbprint property of the UMServer object.
at Microsoft.Exchange. UM.UMService.UMConnectionManagerHelper.TLSConnectionManager.Initialize()
at Microsoft.Exchange.UM.UMService.UMService.OnStartInternal(String args)”
You cradle your head in your hands and begin to weep softly.
- Launch Exchange Management Console from the server hosting the Unified Messaging Role
Important: Remember to launch with UAC elevated permissions!
- Expand and click on Server Configuration
- From the server list in the center pane, select the server hosting the Unified Messaging Role
- In the lower center pane, you’ll very likely notice the new SSL certificate is not assigned to any services
- Right click on the certificate and select Assign Services to Certificate
- In the wizard, check the Unified Messaging (UM) service
- Finish the wizard and dry your tears!
