configure exchange global address book on thunderbird 17

steps:

1.   on thunderbird, go to Tools->address book
2. a new window pops-up. go to File->New->LDAP Directory
3. a new small window pops up.
4. name =
5. hostname = check in outlook. Else, most probably if your mail server is ..com, your hostname for address book will be .com
6. BASE DN = dc=y,dc=com
7. port number = 3268 ( default port 389 did not work for me)
8. bind DN = domain\username
9. do not check "use secure...."
10. click OK
11. right click on the address book you have created, click properties, go to 'offline' tab
12. click "Download Now"
13. you should get a 'replication succeeded" message.
14. To test, compose a mail. go to view->contacts sidebar
15. type some half name in search bar that it shows. suggestions should pop up. Now its working for you!.
16. If you would thunderbird to auto-search names form global address book while you type name in "To" list, go to edit->preferences->composition->addressing, check "Directory server" option and chose the global address book that you just created from the drop down menu. click OK.
17. now open a new mail window, start typing some name, observe suggestions that thunderbird shows up!!! Works wonderfully!
