Outlook 2003 and Base64 file attachments

[Mark]

I searched this newsgroup via Google Groups and search the Microsoft
Knowledge Base without find an answer to this Outlook 2003 problem that I am
trying to solve and find out why it occurs.

There is an e-mail I received from an Outlook 2003 user where the e-mail
sent through an Exchange server containing an Excel spreadsheet attachment.
My Outlook 2003 is not using an Exchange server, it is set up as a POP3
account. When I received the e-mail, the file attachment has not been
decoded in the e-mail as a file attachment. The file attachment encoding is
base64:

------_=_NextPart_001_01C637D0.0DA1B206
Content-Type: application/vnd.ms-excel;
name="FILENAME.xls"
Content-Transfer-Encoding: base64
Content-ID: <[removed]>
Content-Description: FILENAME.xls
Content-Disposition: attachment;
filename="FILENAME.xls"

If this same user sends an e-mail to someone using Outlook 2000 or Mozilla
Thunderbird 1.x, the file attachment decodes and can be saved from the
e-mail.

What in Outlook 2003 is preventing the base64 file attachment from decoding
where I can save the file attachment?

I recently discovered that if a user running outlook does a copy and paste
from the file system to an email the base64 encoding of the file will look
different then if the user does a copy and paste from one email to another.
I'll bet the user has the spreadsheet in an email and does a copy and paste
to a new email before sending it to you. If this is the case have the user
attach the attachment from the file system (no copy paste).
