Dear Team,I'm in middle of transitioning from Exchange 2010 to 2013. Currently we have the following setup:2x Exchange 2010 SP3 HUB/CAS (WNLB, CAS array)3x Exchange 2010 SP3 Mailbox DAG with (2 in Primary and 1 in DR site)1x Exchange 2010 SP3 UM
Lync Server 2013
2x Exchange 2013 CU2 Client Access (WNLB) Ex2013CAS01 and Ex2013CAS02
3x Exchange 2013 CU2 Mailbox DAG Ex2013MB01, Ex2013MB02 and Ex2013MB03-DR (2 in Primary and 1 in DR site)
- I have added Existing DialPlan to all the Exchange 2013 servers and Set the startup mode to TLS. Assigned internal CA certificate and enabled UM service in Exchange 2013 CAS and Mailbox servers.
- Added the same certificate to the Lync 2013 server.
- Moved the Exchange 2010 system mailbox
- Disabled the 2010 Unified Messaging Server via Exchange 2010 EMC
After restarting the Lync 2013 FE server, it gives errors saying unable to find UM Server, Cannot connect to server Ex2013MB01 and Ex2013MB02 with port 5061. Lync Missed call notification email not working.
But when I check the Ex2013 Mailbox servers UM properties, it configured only to listen on port 5063. Port 5061 configured on CAS servers only.
When I get the details of get-UMDialplan it shows only the Mailbox servers under UMServers.
Did I miss any configuration? Is there are any proper documentation/guide when transitioning the UM services with Lync 2013?
Below are the actual error in Lync 2013 FE logs:
