I guess I really don't know what I am doing.
Working on an SBS 2011 Standard machine on subnet 192.168.1.0.
There's a vpn to a remote location 192.168.2.0
A new laptop at the remote site with windows 10 / office 2016 keeps getting an error about the autodiscover.domain.com certificate. It says the name on the security cert is invalid or does not batch the name of the site.
Clicking on view cert, it says it's issued to: domain.com issued by let's encrypt authority x3 with valid date of 8/14/18 to 11/12/18
WE DO have a certifficate for the domain issued by comodo. From a browser, if you type remote.domain.com/owa, you get to the owa page and it says it's secured with the comodo cert.
anyone know where the lets encrypt certificate is coming from?
Other laptops at that remote location are working fine for email.
