cgoodlein,

Have you tried switching the SMTP port to 587?

If it is software as your technician suspects, then it could be a corrupted email profile.

below is a direct link to Outlook's official KB site. i recommend reading through the command switches for Outlook 07 and run the /cleanprofile switch.

Hope this helps.
