Why is There a Winmail.dat Attachment in my Documents?

Objective:

  • Winmail.dat file forwarded in with Email
  • Winmail.dat file attachment forwarded with Email to Maildrop

Environment:

  • Clio Manage

Additional Information:

  • Work around if using MailDrop: Be sure to copy and paste the Matter Maildrop address every time an email is forwarded. Using the saved address within Outlook appears to cause the file to change into a Winmail.dat format. 
  • If you would like to turn off TNEF for Outlook 2010 and later versions (i.e. to stop the winmail.dat attachment from appearing in emails), click here.
