Got an email from an Outlook user with a single "winmail.dat" attachment instead of the real files? Winmail Unpack opens it inside Thunderbird.
What it does
• A "Winmail Unpack" button appears in the message toolbar when an email contains winmail.dat (application/ms-tnef). A badge shows how many were found.
• Click it to see the real files hidden inside: PDFs, Word and Excel files, images, and more, with names and sizes.
• Save one file, or "Save all" into a folder named after the email.
• Also extracts the message text (RTF or HTML) and attachments from forwarded Outlook messages embedded inside winmail.dat.
Why another winmail.dat add-on?
Winmail Unpack uses only Thunderbird's standard, supported add-on APIs (no "Experiment" APIs), so it is designed to keep working when Thunderbird updates every month.
Private by design
Everything is decoded on your computer. No account, no tracking, no network requests, nothing is uploaded.
Tested
Version 1.0.0 was tested on Thunderbird 158 against public real-world winmail.dat samples (Apache POI and tnef project test files): file names and contents matched the originals byte for byte, including long file names, non-English file names and embedded objects.
Coming next (Pro, in development): extract every winmail.dat in a whole folder at once. Free single-message use stays free.
