Our certificate on our Lync 2010 frontend/backend server expired this weekend. I got a new certificate issued by GoDaddy and got it installed ok. We can IM, place calls, and see availability status ok.
Now, however, I get a message on Lync that says 'Server issues are restricting calling ability' and some customers are reporting they can't always call inbound to Lync users. Also, Lync hosted meetings are inaccessible to outside users.
I did not touch the certificates on our edge or threat management gateway servers as their certificates did not expire.
To apply the cert to the frontend/backend server I used the deployment wizard with the lync installer. I did not apply the cert in IIS nor on the edge or TMG servers. It looks like the IIS cert was updated by the Lync deployment wizard since IIS shows the new certificate but I don't know if I can trust it. Don't I have to install the intermediate cert somewhere in IIS? Is this the problem?
I think there is something else I need to do with our edge and gateway servers OR the new certificate to finish this up.
And yes, I've restarted the server.
