In OCS 2007 R2 you might get the following error:

TLS outgoing connection failures.

Over the past 1 minute Office Communications Server has experienced TLS outgoing connection failures 1 time(s). The error code of the last failure is 0×80090322 (The target principal name is incorrect.) while trying to connect to the host “serer FQDN”.

Where Wrong principal error could happen if the peer presents a certificate whose subject name does not match the peer name. Certificate root not trusted error could happen if the peer certificate was issued by remote CA that is not trusted by the local machine.

Resolution:

For untrusted root errors, ensure that the remote CA certificate chain is installed locally. If you have already installed the remote CA certificate chain, then try rebooting the computer.

Cause:

This is mainly because of wrong certificate names, validate that edge and OCS front end have the correct FQDN (((Recently I found that FQDN configured in the OCS 2007 R2 Administrative console on Edge and on the front End is case sensitive and has to match the server FQDN and the Certificate FQDN letter cases so make sure that you have the FQDN has the correct letter cases so EDGE.domain.com is not like edge.domain.com)))
