Check how is configured Exchanges on the SMTP side. How a user must authenticate? Secured or not? The way  SMTP Exchange is configured dictates how to configure mail app

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Hard question as long as I have used Exchange 2003, last time, in the year of 2006 :)

Check for Outlook in Windows how it is configured

Sending and receiving mail are two different things. If you are receiving mail then that eliminates the receive connector. If you arent able to send mail then your send connector is what is the problem. Use the Exchange Console to find the send connector, edit the connector, look for what has been changed, then re/un-modify it so it works. Thats about as specific as I can get without any further details.
