After plugin installation, restart Thunderbird, open address book and choose File / New / Remote Address Book:
Choose a name and enter contact folder location (adjust port to your settings):http://localhost:firstname.lastname@example.org/contacts
Replace email@example.com with actual user email address.
Press OK and launch synchronisation with the toolbar Synchronize button.
Provide your credentials, login is Active Directory account name, i.e. domain\account or email address with Exchange 2007
