I have Lync 2013 and Exchange 2013 installed. Exchange is 3 node DAG, Lync is 2 server pool. Exchange servers are Exchangesvr01, Exchangesvr02, and ExchangesvrDR in another DataCenter. Svr02 was the first one built. Svr01 was added several weeks later. If a UM enabled user's mailbox database is mounted on svr02, they can call the SA number, enter their extension, and get to UM OVA. However, if I move the database to either svr01 or svrDR, when they call the SA number they will get a message saying "Sorry, this mailbox is on a server that does not support Unified Messaging". Moving the mailbox back to svr02 solves the issue immediately. Both servers are on the dialplan, UM service is running, they share the same UM certificate with both servers listed as SAN names.
Anyone have any ideas? I have re-run ExchUCUtil.ps1 and OcsUMUtil.exe.
