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.

Thanks iLse, I follow your troubleshooting guide and solve integration problem as you describe in this article. My problem is that Exchange server certificate subject name is wrong. I request new certificate which subject name is Exchange hostname, then integration is OK. Thanks again.
Nice article Ilse, thanks for the pointers to the documentation too :)
Ok - so following your guide I have it working internally but when I connect via the Internet, I get presence greyed out and no contact list. Appears to be failing to connect to something but I cannot determine what. Any suggestions?
Any option to fix wildcard certificates?`
under data i get fqdn as (*.domain.com)
Ilsa, your blogs on configuring this setup are good starting points, and I thank you for them. however, I'm trying to configure our lab with OWA/Lync integration using the self-signed certs that are configured when the products are installed. Can you give us some guidelines on how this might be completed? Thanks.
Thanks for your excellent post!
One question: Is it possible to archive the IM conversation history also within outlook even if I'm chatting with OWA? Is there a powershell cmd to configure this right?
Any news for wildcard users? Not beeing able to use wildcard certificates is really bothersome.
i face the same error. i troubleshoot all steps. but certficate side i use the CAS owa external name: mail.contoso.com. and my local exchange fqdn is xchange.contoso.com. please help what can i do. i don,t want to purchase new certificate. because external or internal users use the owa address: mail.contoso.com
We were able to get around the public wildcard issue by using an internally issued enterprise cert and using this cert for connecting to lync instead of the public cert linked to IIS.
Thanks for the post Ilse! Are there any other troubleshooting guides for the integration of these apps? We have an issue where some users can see the chat features and some don't (e.g. me).
SAN Names don't work in the cert for this- when i created a certificate with just the subject name to match the OWA directory/trusted app pool name-- and removed the individual CAS servernames it worked!
