Force Outlook 2021 to send TNEF win.dat / winmail.dat

S-Soft 646 Reputation points

How can I force Outlook 2021 (or even 2010/2013 if 2021 not possible) to generate and send TNEF win.dat / winmail.dat ?

Options, Mail, Message Format > RTF
Change "When sending messages in Rich Text format to Internet recipients" to "Send using Outlook Rich Text format"
When sending new message: "Format Text" tab : set "Rich Text"
Add sample stylized text plus attachments plus voting buttons etc and send
Not getting winmail.dat / win.dat :(

Please advise I need it for some purposes

  • I don't have any exchange server email account (with tnef support enabled) if that's needed, know any service?
