Dealing with Winmail.dat attachments

Winmail.dat attachments

Winmail.dat attachments are created by Microsoft email products (Office365 mail, Outlook). Most regular email clients are unable to view these attachments without additional steps.

Users of Thunderbird have a plugin that can be used to help decode these attachments:

Download the file, save it to a known location, and then go to Thunderbird, look for Tools, Add-Ons, and then there's a small gear drop down menu for settings, under which is an option "Install Add-on from File".

Install the add-on, restart Thunderbird, and you should be good to go!
