Created attachment 730575 [details] thunderbird screenshot User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0 Build ID: 20130307122903 Steps to reproduce: A friend sent me an email with a pdf attached. Actual results: I see it as a generic winmail.dat attachement instead of the pdf. Google mail shows it correctly. (see screenshots) Expected results: It should show the attachment like gmail (New Sync-Gen II Manual Release V104 July 2012.pdf)
Comment on attachment 730577 [details] the email That's because it indeed *has* a winmail.dat attachment... Relevant message headers: > X-MS-Has-Attach: yes > X-MS-TNEF-Correlator: <D9D0CF1DEFDCE3468B80294416C3CCAC396C56AF@sgbecmb01> Attachment headers: > Content-Disposition: attachment; filename="winmail.dat" > Content-Transfer-Encoding: base64 > Content-Type: application/ms-tnef; name="winmail.dat" This is a proprietary Microsoft format used in their Outlook and Exchange products. Tell the sender to send "HTML" rather than "Rich Text Format" messages to resolve the issue at the source. Alternatively, there is an extension to unpack such TNEF attachments: https://addons.mozilla.org/thunderbird/addon/lookout/ (may need tweaking to work with 17.0.x, see review comments).
