Hmm, I think that's the autoformatter at work.

Simple question it would seem, but of course the MS Excel Help system is of no use. How do I tell Excel NOT to automatically hyperlink e-mail addresses? I've got someone working on a spreadsheet, and he doesn't have e-mail. So every time he inadvertently clicks a cell containing an e-mail address, he gets a slew of error messages.
