New install of Personal Communicator 1.2 trying to connect to Unity 5.x. In Server Health voicemail says "Failed to Connect - Server Unreachable". All other servers are Green (ok). Unity (primary) is a different server than Exchange message store. Presence server pointed to Unity server using TCP option. On Message store I enabled IMAP and no Windows firewall.
We are using CUPC with our Unity UM. Unity profile in CUPS is pointing to our exchange 2003 server. Everything is working great.
We have now added an Exchange 2007 server to the Exchange Organization and have started migrating mailboxes to it. My mailbox is moved and my CUPC still shows connected and everything is fine but I can not see any voice mail messages. I tried pointing to the Exchange server 2007 but am also showing "Failed to Connect - Server Unreachable"
