Attached templates become spreadsheets
 

I am not sure this is the correct forum for this question, but I do not know
what is.

Using Outlook Web Access, I receive as email attachments Excel templates
with the extension ".xlt" The name listed in the email's attachment list is
correct. However, when I download the template (using the Save Target As
within Internet Explorer), the document somehow becomes a spreadsheet with
the .xls extension.

If I access the email using AOL this problem does not occur (but others do).

Any ideas about how to track down the problem? Or any suggestion for a more
appropriate forum? Thanks
