Sharing Contacts with Outlook Express and Outlook

If you want to have both Outlook Express and Outlook use the same contact list:

1. Start Regedit
2. Go to HKEY_CURRENT_USER / Software /Microsoft / WAB / WAB4
3. On the right side, right click and add a new DWORD key called UseOutlook
4. Give it a value of 1

Now when either the Address Book in Outlook Express or the Contacts in Outlook are changed, each will update the other.
