Users getting a Cert error for their domain in Outlook (using Office 365 E3)
When users open Outlook they are getting:
![1.JPG]()
Checking the cert:
![2.JPG]()
It has been issued by the clients Office 365 domain for the clients Office 365 domain.
I have checked their Domain Controllers and none of those have issued the cert. I have also checked on their Network Solutions account (where they buy all SSL Certs) and its not in there.
Anyone know how to renew?
Thanks

Do they have, or previously had an on-premises Exchange server? If so, you need to update the certificate on the autodiscover ednpoint, or remove it altogether. If they dont have any Exchange boxes, the autodiscover response might be served by the hosting company, there is a well known "issue" with cPanel-based solutions "hijacking" requests.

Hi Vasil
No on-prem exchange server for this.
How can I troubleshoot the autodiscover side?
