Today I added in a new Exchange Server for redundancy and went through all the steps. I created a new certificate requested and got my 3rd Party cert. Upon completing the process I got the error above.

Funny thing is I was able to assign services to this certificate. I ran the following commands from a standard command prompt:

  • certutil -urlcache ocsp delete
  • certutil -urlcache crl delete

After that I hit refresh and certificate is now valid. No more errors reported.

Hope it helps
