Simple as it gets I suppose.

We have &nbsp;a main office with an SBS 2003 server serving exchange to the organization. &nbsp;Recently we've opened a remote office across the country.<br />
<br />
Main office: Domain 1 w/SBS running exchange<br />
<br />
Remote Office: Domain 2 - users need to connect back to Exchange on Domain 1.<br />
<br />
Currently I have the two offices connected VIA VPN and everyone can access shared data between two offices. &nbsp;They can also connect to the Exchange Server via Outlook only after inputting their DOMAIN 1 user info each morning. &nbsp;<br />
<br />
Is there any way to make the remote users connection to the DOMAIN 1 exchange server seamless so that they are not continually needing to authenticate?

Connect Remote users to Exchange server without the prompt for password

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).
