Mailbox Security

Running Exchange 5.5 SP3.<br>
<br>
Any user may access all or any mailbox they want. NT Password Authentication is not working. Am I missing something?<br>

from any outlook 98 client. Any Joe can read anybody's email. I think it might be an Exchange setting that I am missing. All the clients should be using NT Authentication on the client side. There must be something that tells the server to look for NT Authentication.

The only users that should have access in Exchange Administrator are administrators. Check the Organization, configuration container, and server object permissions to see what groups have permissions.
