This question came from our site for system and network administrators.

Try the script on this page:

Also are your Exchange server and Office 2011 fully updated?

Yes, everything is updated. still not working – Prashant Apr 27 '11 at 19:07

Error -18597 means Outlook is getting an HTTP Error 403 from the Exchange server. You probably have incorrect credentials or something strange on the Exchange server. Check the logs on the server for more details.
