Not sure exactly what category this falls into, so I'll try them both. Anyway, working in Excel 2000, when I try to send the file as a mail attachment, the Internet Connection Wizard pops up asking for my SMTP and POP information. The problem is, I'm using Exchange. When I go to Program Access and Defaults, Outlook 2000 doesn't even show as being installed, only Outlook Express. I re-installed Office 2000, and I still get the same problem. I even disabled the access to Outlook Express, and when I tried to send the file again, it said I had no mail clients installed. Sound familiar to anyone? I sure hope so. Thanks for your time!
