I recently set up Exchange Server 2003 for one of my users. They share a mailbox so they can share contacts, calendar and email inbox. For demonstration purposes on this post I'll call their domain abc.local. They have a satellite provider for their internet access, and they use pop mail to send and receive email using the satellite provider's email server. I'll call that email address xyz@direcway.com. Pop mail is the default email service on both PCs. xyz@direcway.com is set up as the reply address on both machines. For the most part they can send and receive email and the recipients get the email from xyz@direcway.com. Occasionally the recipients will get an email from name@abc.local, not from xyz@direcway.com. On other occasions they'll recieve a return email from the System Administrator stating that their messages were undeliverable. Is there any way that I can turn off the email function in exchange server so I don't have to worry about them sending from the wrong account? Or, do I have something set up incorrectly? I'm pretty sure I didn't enable any email settings on the server, but I'm very new to Exchange server, so I might have done something to cause it to behave like it is. Any help would be appreciated! Thanks, Dave
