I want to create a certificate for Exchange
I am running wass.exe as administrator
I select the type of verification - [http-01] Serve verification files from memory
But when validation is run I get an error: invalid response from http://autodiscover.mydomain.ru/......
Right now I'm using office365
On the external DNS, I have a CNAME entry for autodiscover
Do I need to make a type A record on the external dns for my exchange server?
