We've got a user who has sent two emails that have only part of the message sent. Before sending one of these emails, she carefully checked it for spelling and grammar error. Everything was okay and she sent the email. Later, she checked the sent items and saw the email that was sent only contained part of the email. It's as if the email was sent was sent from an earlier version, of the email and hadn't updated. No one else has had this problem.
User is using Outlook 2003, which is fully updated.
