I am running Excel 2003 and yesterday I emailed (using Outlook 2003) twice to
different addresses at the same client with .xls attachments. Both times the

a test, it arrived with the attachment OK and uncorrupted. Any ideas? is it
their virus protection maybe?

I would suggest that you are sending in Rich Text Format and your
clients are not using Outlook as their email client. Try sending using
plain text or HTML format instead.
