Outlook - Certificate has been revoked
Was resolution ever identified for this problem? I have the exact same issue with the exact same certificate. I opened a case with Microsoft support but they have not been any help so far.
No changes have been made to our network, the CRL isn't being blocked by anything, it doesn't contain the serial number of the certificate in question and the problem is intermittent.
Unfortunately the cause was never found. MS was able to reproduce it twice on their end but didn't get the required logging. After that it didn't occur anymore.
As we didn't change anything on our end, I had a suspicion they fixed it silently in one of their updates recently. Have you tried updating Outlook to the latest update?
Thank you for the response.
I'll test updates to see if that helps.
