I cannot send e-mail is the person is not in my address book?

[SpiritWrkz]

For some reason sometimes whn I use an address list that is seperate from my
outlook contact list it says people are invaild. Cometo think of it even
people in my address book are invalid.

You will need to provide your Outlook version and far more complete and
accurate detail of your problem. We can't read minds.
