Worksheets Don't Properly Send When Emailing
 

At first, when I tried to email worksheets directly from Excel, they sent
just fine. Then, only a line or two would send. Now, nothing sends at all.
(As in, recipients email me back asking where the data is.) My coworker is
also having this problem. We don't mind simply attaching the spreadsheet via
a new mail message, but emailing directly from Excel was convenient. What
might be causing this problem?
