I've been tasked with looking at several different mailboxes and notating who has FullAccess permissions to these mailboxes. Just about everything I find online references this the other way around: "What mailboxes does user X have FullAccess rights to". In my scenario, I do not know who the individual users are; but only the name of the mailbox itself. Ultimately, I'd like to be able to run a powershell script that would filter out everything except the users who had FullAccess rights on that particular mailbox and export it out to a .CSV. I've tried several different scripts and commands but I still am unable to get the exact output I'm looking for. Any help would be much appreciated!
