when trying to open excel spreadsheet files in outlook express, i get the message
outlook needs to know what file created it.


If the person sending is using Excel under MS Works then the file extension will be .XLR
If they use Excel under MS Office then the extension will be .XLS

It stands to reason that you will need one or both of these programs.
