I know where is a problem (Outlook and RTF mail format -- see https://www.novell.com/communities/coolsolutions/mystery-missing-e-mail-attachments/) but I want to know if there is a possibility to set up GWIA or something else users be able to see winmail.dat as attachment.
Today users can see a message (from, subject, text) but no attachment. Only source of message tab shows raw email where we can see there is a Content-Type: application/ms-tnef named winmail.dat.
Thank you for your co-operation. I appreciate any hint.
