I'm absorbing a company into our exchange and added them as an accepted domain. There current certificate is pretty standard mail and autodiscover SAN names. Currently RPC over http is not working correctly and that is to be expected since I pointed there DNS record for autodiscover to my server. I don't have autodiscover.theircompany.com in my certificate, so it's trying to resolve a name that doesn't exist. My question is should I add a SAN name for autodiscover.theircompany.com to get RPC over HTTP to work correctly?
My SAN names would then look like this:
mail.mycompany.com
autodiscover.mycompany.com
legacy.mycompany.com
autodiscover.theircompany.com
Would this be accurate or is there a better method?
Thanks!
