Email converted to winmail.dat when sending

When sending emails using my add-in I'm tracking some info using a user property, but when the email is sent the contents are changed and a winmail.dat file is attached by outlook.

I've tried removing the property in the send event as is suggested in some other topics on here but that doesn't seem to work. Is there any other way to disable outlook from converting it to a winmail?

Hello Jamie,

To avoid that, create a named MAPI property using MailItem.PropertyAccessor instead, see https://msdn.microsoft.com/en-us/library/office/ff863046%28v=office.15%29.aspx.

Hi Andrei,

I've tried using the PropertyAccessor you suggested but because I need to support older versions of Outlook, neither the Outlook.PorpertyAccessor or MailItem.PropertyAccessor exist. Is there a different solution that I can use that will work on everything back to Outlook 2000?

No universal solution exists. In Outlook 2000-2003, you can use Extended MAPI to create a named property. I suggest that you google for such code.
