Has anyone ever tried to get access to a mailbox in another domain using local domain credentials?
I have 2 domains (A & B)
There is a two way trust between the domains (different forests)
Domain B is running Exchange 2010.
A User in domain A wants access to a mailbox in Domain B.
I successfully grant access on the Domain B mailbox to the domain A user.
I go to Domain B's OWA page and successfully log on as Domain A's user.
I get an (expected) error (~you don't have a mailbox~)
Then I try to change the URL to include the target mailbox but I can't get to it. (access denied)(https://server.domainB.com/owa/mailbox@domainB.com)
The company is in the middle of a MASSIVE email migration and I'd rather not create an account in the target domain for this user and go through all that mess.
Thoughts?
Thanks in advance,
Gene
