Hello!, i'm going to explain my issue with autodiscover and Exchange 2007:
Exchange 2007 CAS w/autodiscover set to: mail.domainA.com
Client machine w/outlook 2010
Exchange 2010 CAS w/autodiscover set to: mail.domainB.com
I configure the outlook on the client computer on "Domain A" with RPC over HTTPS of "Domain B".
There is no problem of conectivity, I send and recieve mails, but if I close the Oulook, the Exchange Proxy Settings change to Domain A and I can no longer login again on the outlook with the Domain B account.
I cannot kill the Exchange on the domain A because there are other mail accounts that we cannot move.
