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?
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.
