I've inherited an exchange server already setup before me. I've found that any user can open up any other users inbox by using outlook by going File-Open-Open User's Folder. I've found that this is not the default behavior of outlook but can't find exactly where to change this permission. When I look at the Mailbox Rights from the Exchange Advanced tab using AD, I find there is an everyone group with inherited permissions to read, change, take ownership and full mailbox access. Is this the problem? If so, where do I change it since it is inherited? Thanks
