Sending emails from contacts Outlook 2007

[Dave]

When I try to send emails to multiple people in my contacts, the email goes
to the outbox. Some of these contacts were created in earlier versions of
Outlook, and some transferred from other PCs. If I remove certain contacts
from the email, it will send. I have looked over the contacts, and see no
problems with the email addresses or any other information. It seems to be
specific to certain contact, but not all of them.

Is there something I can do to repair my contacts, or to resolve the sending
issue?

I believe this has somthing to do with the Autocomplete option when typing a
persons name in the To:, CC:, or BCC box. Checking to see if deleting
recipient will clear the problem.
