Need to find what calendars user has access to
by ArmyCommander6948
User is having issues with calendars that users have previously shared to them, or they have because of Shared Mailboxes etc. So, I'm wanting to easily find a way who the owner is of those calendars. As far as I'm aware there is no feature like this inside of the GUI on any 365 Admin Center. I've tried a few Powershell commands such as Get-EXOMailboxFolderPermission -Identity UPN:\Calendar - This command obviously only outputs the User's owned calendars, and not if it is shared. Plus there is 100 Mailboxes within the tenant. Is there any way to figure this out? submitted by /u/ArmyCommander6948 [link] [comments]
