I have an enviroment consisting of an exchang 5.5 and an exchange 2000 server with ADC running during our migration. While migrating mailboxes we noticed that the users are able to access others. After checking permissions I found that the mailbox rights on the Advanced Exchange properties of the user in AD had the everyone group with inherite permissions.
I have been able to trace the permissions back to the mailbox store. This seems to be where they where added.
My questions are:
Is this something that the ADC or mixed mode has done for the purpose of the migration and once removed and set to native mode will be corrected? Or do I have to go and beat someone in the admin group for adding permissions that should not be there? If the later is the case. Is there ANY permissions for the everyone group at this level normally?
Let me know if anyone has any info on this. From the searches through the maze at microsoft I can seem to get a strat answer.
