From field not auto-filling

[Craig]

The From field on Outlook used to always auto-fill with my email address, but
for some reason it no longer does. Recepients seem to be getting it, but it
does not appear when I start a New or Reply message.

You asked the same question yesterday and got multiple replies; have you
read those answers already?
Long story short; there is no need to manually specify the From field for
each message. It is only needed when you want to send as/on behalf of
somebody else.
