Running on Windows Server 2003 R2 - We have a legacy MAPI mail service which emails PDF reports outbound as attachments. The emails are being bounced back from a external reciepient because of two attachments winmail.dat and winpart.dat. I understand the message is being sent in rich text format and this is the underlying cause. Is there anyway I can change this mail to plain text?
I've found this
#define MAPI_SEND_NO_RICH_INFO ((ULONG) 0x00010000)
but not sure where or how to edit the mail formats.
Any help appreciated.
