We have a user in our organization who, when she sends an email with an attachment, the recipient gets 'winmail.dat', instead of the attachment. I know the normal causes of this, which we've checked out already (rich text vs. html, etc.). The thing is, she can forward an email with an attachment to someone else in the organization, who can send it out fine to the recipient, who gets the correct attachment.
At the suggestion of another technician, we created a new account in Active Directory for this user, and she started using that instead, but the problem remained. We have an inhouse exchange server (2003), if that helps.
Thank you for any help you may be able to provide,
Peter J. Squicciarini
