Error message: This file must be converted with BinHex 4.0
 

I get this error message and a scrambled document when trying to open Excel
files via web mail that were created on a MAC . I run Win XP Pro with SP 2. I
have not had this problem on my home desktop dl'g with Outlook Express. So I
don't know if the problem lies within my laptop or the webmail or the MAC
creator's Excel version or???
Thank you for any help.
