Thanks, and I have been all over that article already.<br />
It does not reference renewing a cert on Chat.<br />
<br />
I have manually requested a new cert from mmc, and have a new cert on Chat, but Lync is not accepting it, which is the issue. Even though I restarted Lync.<br />
The error in Skype reads &quot;you chat room access may be limited due to an outage&quot;<br />
<br />
Whats interesting is in Lync, there is not cert from Chat, the only cert that existed is on Chat.

Our internal Chat server cert recently expired. Skype for business group chat has stopped working. <br />
Skype for business 2010.<br />
Does anyone know how to renew a certificate between the Chat server and the Lync server ?<br />
Both are housed internally in our building.<br />
<br />
Thanks!<br />

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.
