Hi,<br />
Well create Transport Rules to achieve the same. Basically if there are more than 2-3 users, then create a Group called DenyExternal (sth like that) and put these users in that Group. Now create TR and sliently drop mails for anyone in that group. Same for outgoing external mails from these users drop them<br />

I have a client running Exchange 2007. &nbsp;They have 1-2 users that they want to restrict their email account to only be able to send and receive email within the network. &nbsp;They dont want these people to be able to send email to anyone outside the network nor receive any email from outside the network. &nbsp;I have experience with Exchange 200/2003 but very little in 2007. &nbsp;Thanks for your help.

They dont want these people to be able to send email to anyone outside the network nor receive any email from outside the network.  I have experience with Exchange 200/2003 but very little in 2007.

How do I Restrict Send/receive in Exchange 2007 to internal domain only

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

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

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.
