I have run into a little issuing while using Microsoft’s Lync 2010. It all started when I logged into a test workstation. After my testing of this awesome product I signed out. What I noticed was that my log-on info was still there and I was able to log into Lync. I would like to stop this but to my surprise could not find any place to remove this.
To my surprise I come to learn that Lync stores this information in a certificate that is stored in the local store of the computer. Okay, now what?
I did some Google searching and found that I could change the validity person of the cert; found here, but this was not what I was looking for. I want to remove my log-on info.
To remove your info you need to do the following:
Open Windows Certificate Manager.
To do this, click Start, click Run, type certmgr.msc, and then click OK.
Expand Personal, and then expand Certificates.
Sort by the Issued By column, and then look for a certificate that is issued by Communications Server.
Verify that the certificate is present and that it is not expired.
Delete the certificate and try to sign in to Lync.
