I tried to send a presentation to someone for reviewing. In PowerPoint, I clicked Send To and then Mail Recipient (for Review). The message window opened, and my presentation was attached to the message like it was supposed to be. I entered the e-mail address of the person and clicked Send after connecting to the Internet. After I opened Outlook, the message appeared in my Outbox, so I opened it and clicked Send. It looked like it was doing something, but my message didn't appear in the Sent Items folder, and the person I tried to send it to didn't receive it. I wonder if this has something to do with the fact that my default e-mail is usually Outlook Express, and I had just changed to Outlook in the Tools-->Internet Options-->Programs dialog box. Maybe I should have rebooted after I changed to Outlook? Please help!
