Am I right in thinking there are 3 unique ways to share access to a mailbox to other users. 1) Via AD permissions ***what is this called in terms of exchange access mgmt*** 2) In Outlook via delegate rights 3) In Outlook via right clicking the root of your mailbox and configuring a setting in the sharing option? ***What are these called*** Is there anyway to get a cumulative report of who can access a specific mailbox via these 3 methods? And if these are all unique ways, why is there a requriment for 3 different ways, do some give other fetures that the others dont?
