When you save your Excel product, are you saving it as a .xsl product?
I had that problem at work and have to save them as .xls not .xlt
Hope this helps.
I use BTYahoo email and having tried send an excel spreadsheet as an attachment to an organisation I they tell me they cannot open the attachment. Private receivers have no problem. I then attempted to copy and paste the document to the text of the email, again they say not able to open. I did test this by sending to myself and was able to open even though the document had not retained the formatting it was sent in being spread all over the page. There must be a way of including a document as part of an email so that it arrives in the same condition it leaves me. But what is it??
