Good day everyone,
Run into an issue with a site I do IT support for, of course the day before vacation.
So the site has a single Server acting as the DC and their Exchange Server, and within the past couple of days its come to its first certificate renewal. After the certificate renewed all of their users began getting a security alert pop up giving this for a run down:
Information you exchange with this site cannot be viewed or changed by others. However, this is a problem with the site’s security certificate.
(check mark) The security certificate is from a trusted certifying authority
(X) The security Certificate has expired or is not yet valid
(Check mark)The security certificate has a valid name
Viewing the cert shows it was issued to autodiscover.mydomain.ca, issued by R3, Valid from 3/24/2021 to 6/22/2021. So obviously still trying to use the old certificate.
Now I’m running Certify 22.214.171.124, it shows the certificate for autodiscover.mydomain.ca will Expire in 89 days. If I go under Managed Certificates> Advanced> View Certificate it all looks correct there and give me the option to install it, which I have clicked but still shows install cert afterwards.
If I go into IIS Manager and check my certs in there, I can see it showing the certificate with an expiration date of 9/21/2021.
I currently can’t access the EAC for Exchange due to this certificate issue.
Can anyone think of anything I may have missed?
