Q: How do I disable AutoComplete in Microsoft Office Outlook 2007 and Outlook 2003?

A: I have a client who’s a partner in a law firm that runs Outlook 2003 and Exchange Server 2003. I showed him a recent article I thought he’d find interesting, “Lilly’s $1 Billion E-Mailstrom,” by Katherine Eban, on Portfolio.com, http://www.portfolio.com/news-markets/top-5/2008/02/05/Eli-Lilly-E-Mail-to-New-York-Times, about an email problem experienced by another law firm. Someone in that firm wasn’t paying attention and sent a confidential email message to an unintended recipient with a name similar to the intended recipient’s. Instead of going to a lawyer named Bradford Berenson, the message went to Alex Berenson, a New York Times reporter. The confidential content ended up on the front page of the New York Times, in the story “Lilly Considers $1 Billion Fine to Settle Case,” on January 31, 2008. . . .
