How do I add "from" to my letter page

[Dancer]

I have Microsoft outlook 2000. I added an alias and want to use it for
mailing. But I don't have a "From" on my mail page.
I have To, Cc, Bcc, Subject?

How can I add "From"

Create a new mail message and select the View menu, then From Field.

Cheers
