Problem:
Messages sent from Outlook 98 or Outlook 2000 that contain an attachment are received in Notes with a C.DTF or ATTXXX.DAT attachment. Messages that
contain no attachments from Outlook are received with no problems.
Solution:
Check to make sure the person sending the message from the Outlook client is not using Microsoft Exchange Rich Text Format. If the user's address is in the
Personal Address Book, deselect the checkbox labeled: "Always send to this recipient using Microsoft Exchange rich text format" in the Personal Name & Address
Book (on the SMTP - General tab).
Also, check the outgoing email message from Outlook to see if the message was addressed to more than one recipient. If one recipient message is formatted using
Outlook rich text and the other is not; the recipient receiving the message using Outlook Rich Text will not receive the message correctly while the recipient not
using the Outlook Rich Text format will receive the message fine.
This issue was reported to Lotus Quality Engineering and it was determined not to be a problem with the software.
