I am using Outlook 2010. I recently upgraded from 2007. In OL2007 all of my
contacts were avialable in the address book, so when I clicked New Email and
then Send to, all of my contacts were available.

In 2010, the address book is empty, so there is nothing in the box when I
click the send to.

When I look at the Contact Folder properties, Outllook Address Book tab, the
"Show thsi folder as an email address book" checkbox is greyed out and not
clickable.

This is evidence you did not transfer your data from Outlook 2007 to 2010
properly.

Not sure what to do next.

You need to create a new mail profile. That's the only way to correct the
broken Outlook Address Book service so that it can access your Contacts.
