Question : "Winmail.dat" Attachments?

For some reason, from certain senders, all attachments show up as "winmail.dat" .  I need to know how to fix this as when the same message is sent to an XP machine in the same office everything show up fine.  If forwarded from the XP machine the message shows up fine.  The "www.winmaildat.com" reader does not work.  I have tried all the resolutions on the Microsoft KB and nothing seems to work, please help.  Not all of the emails show up like this just ones from certain senders.  

Answer : "Winmail.dat" Attachments?

I have found a solution.  And its easy.

1. Export a .pst file from the effected account.
2. Create a new profile in the Mail tab in control panel.
3. Setup profile and import the .pst file you made.
4. Problem solved.

Wish someone had told me that before the headache started.
Hope this will be helpful to others.
