What version of Outlook? What type of email account?

It sounds like the address book is corrupt. If you use outlook 2003 or
older, try this: go to Tools | Email Accounts, choose View or change
existing directories or address book. Remove Outlook Address Book and close
then restart Outlook and repeat these steps to add it.

...
Every time I try to send a text message per Outlook, I can type and send
the
message, only as long as I physically type a person's name in the To box.
If
I click on the little address book button beside the To box or click on
the
icon at the top of the message page, I immediately get kicked out of
Outlook,
and it must restart.

Does anyone know what is wrong and how it might be fixed?

Thanks,
Candy
