I have a task to audit who can access 3 of our team mailboxes, regardless of how the ex admin/mb owner set their permissions. I am concerned just how many ways there seem to be to share a mailbox. 1) Are the permissions set via tools >options>delegates the same as those permissions listed if you right click the root of the mailbox, >properties>permissions? Or are these 2 different ways. 2) If they are different what is the technical name of those permissions set via root of the mailbox, >properties>permissions called so I can research further 3) Am I right in thinking you can set permissions via 3 ways - active directory, delegates, or the right click method? If so if you set them in all 3 places for the same user/group, which takes effect, as surely they can conflict? Is there any free way to identify permissions set via all 3 ways?
