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?

Hi Ilsa,

Any news for wildcard users? Not beeing able to use wildcard certificates is really bothersome.

Hi,

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

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!
