The autocompletion cache has nothing to do with your Contacts.
Outlook does not lose data. Users lose data. You must have some idea what
happened. What happened will determine whether you can retrieve them. If you
inadvertently deleted your Contacts, they would be in your Deleted Items
Folder. If you deleted them from there, they are gone and you would have to
restore them from your most recent backup.

I have VISTA Business and have been using Outlook 2007 for a number of
months. Suddenly, I lost my contacts folders and all the information in
it.
I have been able to get the contacts folder back, but the folder is empty.
I
know the information is somewhere in the computer because when I send
email
and start typing in names choices from my address book come up. How do I
find all the names.
