When you enter text into an e-mail, Outlook recognizes certain values, such as Web and UNC addresses (such as a network resource), and automatically makes them hyperlinks. However, after you enter a space, Outlook stops creating the hyperlink because it has no way of knowing whether you've finished the address and are now typing another word or whether the address contains spaces.

Sometimes you just need to have a quick preview of an email before deciding whether to open it. Outlook provides a feature called AutoPreview that shows the first few lines of your emails.

If you want to construct a more complicated distribution list, with some recipients on the To field, some recipients on the Cc field, and yet more recipients on the Bcc field, you have to use a message template where you explicitly assign recipients to each field.
