Received a lot of feedback on one of my previous blog posts, on how to configure Lync RC and Exchange to enable OWA as a Lync Endpoint:
Configuring Lync RC and Exchange 2010 Sp1 to Enable OWA as a Lync Endpoint
And it seems a lot of you are experiencing the same problem I had when configuring it, being, you log into OWA, you get presence for your own account, and the Contact List appears to be “expanding”:
But after a while the following error message shows up: “Instant Messaging isn’t available right now. the Contact List will appear when the service becomes available”…
Time to troubleshoot, and here are the steps to follow…
Log into your Lync RC server, and launch the Lync Server Logging Tool
And check that you want to log All Flags for the SIP Stack, and then click Start Logging.

Have a close look at the given error message! In my case it clearly pointed out that the Peer “cs14ex.lync.local” was not a configured server on this network interface, which was right since I hadn’t added cs14ex.lync.local as a CsTrustedApplication yet.
