Attachment issue when sending email to Document Library

[kk5]

The issue i have with one user is
User sends an email with attachment(outlook 2003) to a sharepoint site. but only the email is delivered, not the attachment.

I tried sending from my account and i was able to see both the attachment and email in the document library.

Asked the user to login to my machine and use outlook and she was successful in sending both attachment and email to Doc Library.

My question is what outlook settings are different on my machine and her machine which is preventing her to send the attachment to the Sharepoint Doc Library.

Appreciate your help

Thanks
