Hello everyone, I have Outlook XP. I am currently having problems sending mail attachments to people, especially hotmail users. What happens is when i send an attachment what every file type etc.... it is received by the other person as a winmail.dat file which they cannot open, as windows does not recognise the .dat or does not know which application to run it in. Why does this happen ? Does any one know why its doing this and how to resolve the problem.. Many thanks for everyone’s help in advance... Regards Team434 :-)

Hello everyone, i just found this which explains why its doing it !!! I hope this helps anyone else having the same problem ! thanks Team434 When an end user sends mail to the Internet from an Exchange Windows or Outlook client, a file attachment called Winmail.dat may be automatically added to the end of the message if the recipient's client cannot receive messages in Rich Text Format (RTF). The Winmail.dat file contains Exchange Server RTF information for the message, and may appear to the recipient as a binary file. It is not useful to non-Exchange Server recipients.

thus i will turn off Rich Text Format (RTF) in Outlook !! :-(
