Outlook/Exchange Issue

We are migrating teachers to a Windows 7 laptop from an old XP tower in a small private school.  Both are using Outlook 2007.  We are experiencing an issue involving replies to emails from outside the domain.  They don't send.  However they do send from the XP box.  Is there a setting we need to be aware of?

To summarize:
1) They receive emails from anywhere.
2) They can send emails to anywhere.
3) They can reply to emails from domain addresses.
4) Replies to non-domain addresses don't reach their intended recipient.

In Outlook, click on File > Options > Mail
Scroll down and click on "Empty Auto-complete List".

Sometimes this gets corrupt, and even though you're not explicitly pulling information from that list, Outlook may pull it anyway on a reply.

Not sure what you mean by Replies to non-domain addresses don't reach their intended recipient. Could you be more specific?

Is your SMTP server set up with a whitelist of IP addresses or hostnames that can send?

1. Could be the Windows XP machine is not using a true Exchange connection and is using either IMAP or POP with a different outbound address to send mail.

2. The Windows 7 machines could have some sort of Antivirus Outlook plugin or firewall that is blocking these messages.

It appears to be a user-by-user issue because mine works fine.  Could it have to do with there being too many items in their folders?  One person who is struggling has 1200 items in her inbox.

1,200 items in the inbox is never great, but I have seen users with thousands more and not have trouble sending.

Can this user log in at a different PC (preferably one they have never used before) and send and receive normally?  If so, I'd suspect a bad mail profile on the troublesome PC - check in Control Panel.. Mail..
If so, you can delete and recreate this mail profile.  You can even create a new temporary one first as a check.  

it never hurts to have a known working backup of the mailbox as well.  Even an Export to PST can be worth doing - all mail folders, including Calendar and Contacts.  

And no, the size of mailbox will have no bearing on the issue.  It just makes sorting and searching slower.

She is on her second machine Windows 7 machine, and on her current one I uninstalled and re-installed office.  Same problem...can receive and send but replies die in cyber space...no error message...they just don't go anywhere.  Having said that, she can reply on her old XP box.
