  2. If you use Dexterity custom code to send an e-mail message that has a PDF attachment, the PDF attachment is sent as a .dat file or is missing

If you use Dexterity custom code to send an e-mail message that has a PDF attachment, the PDF attachment is sent as a .dat file or is missing

Symptoms

If you run custom Dexterity code that uses the MAPI_Send() function to attach a file in PDF format to an e-mail message, you experience one of the following symptoms:
  • The file attachment appears incorrectly as Winmail.dat instead of in the PDF format that you selected.
  • The file attachment appears to be missing even though it was attached to the e-mail message.

Cause

The Microsoft Exchange Server settings may cause the attachment to be sent in RTF format.

Client e-mail systems can receive e-mail messages that have an attachment. However, if the e-mail systems do not support RTF, the attachment cannot be separated correctly from the body of the message.
