- This article was written for Thunderbird but also applies to Mozilla Suite / SeaMonkey (though some menu sequences may differ).
Outlook uses the Transport Neutral Encapsulation Format (TNEF) to send messages with Rich Text Format (RTF) formatting. If your e-mail client doesn't support TNEF (most don't) you also recieve a winmail.dat attachment. Sometimes you may receive an attachment with a generic name such as ATT00008.dat or ATT00005.eml instead. You can configure Thunderbird to use one of the programs below to open the attachment.
- Fentun Win9X, NT, and Win2K but not Windows XP
- AkeeSoft WMViewer Windows 95X though Windows Server 2003
- Winmail Opener Windows 95X though Windows Server 2003
- TNEF Linux
- TNEF's Enough OS9 and OSX
The sender can avoid sending a winmail.dat file by turning off TNEF in Outlook.
- On the "Tools" menu, click "Options", and then click the "Mail Format" tab.
- In the "Send in this message format" list, click "Plain Text" or "HTML", and then click "OK".
