Using Reckon Accounts Premier 2018 and upgraded from Outlook 2007 as I thought that was the reason, to Outlook 2016.  Both running as Administrator.  Outlook 2016 settings to HTML etc. but no joy.  When I check the messages sent in Sent Box they show as PDF but recipient has them in win.dat format.  Contacted Outlook support who happily told me it was a Reckon error.

To prevent Outlook from attaching winmail.dat when you send an email:

  1. Click File in Outlook.
  2. Select Options.
  3. Go to the Mail category.
  4. Make sure HTML or Plain Text is selected for Compose messages in this format: under Compose messages.
  5. Now make sure Convert to HTML format or Convert to Plain Text format is selected for When sending messages in Rich Text format to Internet recipients: under Message format.
  6. Click OK
