The senders of mails with winmail.dat attachments are usually totally unaware that their mail-client is sending these. Therefore, asking them to deal with it will not usually render much result as they are unaware that there is a problem. After all, they never see this attachment on either incoming or outgoing mail.

Outlook incorrectly assumes that all recipients you are in contact with are also using outlook. As soon as Outlook thinks it needs to send additional information with an e-mail, or if the sender adds attachments, these get encoded into MS/TNEF format which only Microsoft's e-mail software recognizes (AFAIK, I have heard that the new release of the GroupWise Internet Agent will support this, apparently Novell decided to support this non-standard attachment type to get rid of all the support calls I guess this must generate). There is a tool called Fentun (http://www.fentun.com/) which is free and which will allow you to open winmail.dat files and extract the attachments stores within it. Note that smaller winmail.dat files usually contain nothing but additional MS-proprietary mail attributes and no attachments, in which case Fentun will show now file-list. -- Greetings, Maurice Using The Bat! v1.63 Beta/7 on Windows 2000 5.0 Build 2195 Service Pack 3 ________________________________________________ Current version is 1.62r | "Using TBUDL" information: http://www.silverstones.com/thebat/TBUDLInfo.html
