Exchange connectivity test fails when certificate doesn’t match name

Leave a reply

I had a scenario where I was using a single name SSL certificate which was setup for mail.domain.test. I needed to get autodiscover to work for this domain name. The DNS host was Godaddy.

I configured an SRV record as follows:

The target pointed to the certificate name. EG: mail.domain.test. This allowed the https://testconnectivity.microsoft.com test to go through.
