Sending e-mails (without automatic security interference all the time) and scheduling things in Office applications are both very large subjects in their own right.
A "little" question covering both is far from that (little).
I can point you at a thread (
Outlook : Select Address of a Contact) where some of the e-mail details are discussed (including some helpful links).
If you want to know about scheduling I suggest you post a question in a separate thread on that subject, but don't expect either question to be straightforward.
