we use multiple domains with ZCS.
One of them is our internal management domain with the "shared-user" (the one who shares companywide calendars and contacts).
Via WebInterface, I can open and use the shared-calendar without problems.
But Outlook won't let me open it, because it's not in the address list (different domain than my outlook user's domain).
How can I make Outlook open a mailbox which is not in the same domain like me?
