Totally agree, in an AD environment with all the trusts in place there's no reason why you can't add a user account from another domain to the mailbox permissions.

We have Exchange 2003 server in domain A (say). Can we give users in domain B (a domain in another AD forest but which is fully trusted) rights to mailboxes on Exchange in domain A?<br />
<br />
I think the answer is no, but want to be sure. (In the current setup, users have to logon twice, once to their domain B and then to domain A for Outlook. We want to eliminate mulitple logons.) Thanks.<br />

Can a user in other AD domain logon to Exchange 2003 mailbox?

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
