Why not have a shared mailbox named as Department with SendAs and FullMailboxAccess rights to the users and few more is that you can have the Shared mailbox forward emails to a DL.<br />

Shared mailbox with sendas rights is going to be the best (least administratively awful) way for you to achieve this. You can also prevent the users by sending externally by utilising transport rules (this blog note assuming you have at least Exchange 2K7)<br />

Hi,<br />
<br />
In our Company we have Users ( james@contoso.com) and Departments (Distribution Groups: administration@contoso.com<wbr />).<br />
<br />
Our clients must send emails to departments, not users. <br />
<br />
This why I´d like to send internal mails as users, but when a user want to send a external mail user name (james@) change to departmen name (administration@). &nbsp;This way, the clients will receive a department email, not a user email.<br />
<br />
How could I configure exchange to do this?<br />
<br />
Thanks<br />

Send internal mail as User, Send External as Department

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

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.
