Missing attachments in Outlook 97

I have a user that is having problems sending attachments to particular external email addresses. She is sending simple Excel spreadsheets to these intended recipients, and all they receive is an attachment with the following name: ATT00003.dat. If this particular user forwards the same message to someone in her department, and they send it to the recipient, they receive the email with the Excel spreadsheet attached. Both users at my company have the exact same Outlook client setup. They both use similar machines configured the same. She was initially using Word as her email editor, but we changed it to Text and Outlook Rich Text. Still the same problem existed. I have completely uninstalled the whole Office Suite to no avail. Please help.

 

Sounds as if your attachments are being sent using UUEncode

Try sending the files as MIME:

1. Open the message and attach file as usual.
2. Click File then Properties option.
3. Click Send Options button
4. Change attachment format to MIME
5. Click OK then OK again.

 

I looked at the Send Options, and MIME is set as default for all messages. Any other ideas?

 

Well poop...that usually fixes the problem. I'd say try changing the send options to UUEncode but I'd very suprised if that works. You might compare vesions of Outlook, maybe one is the original version and the other is at SR-1 or SR-2. Anyone else have any ideas?
