I am trying to troubleshoot an issue with my calendar permissions. users can review all the fine detail of all my meetings/appointments, and I cant figure out where this has been set.
For example, reviewing the output of: Get-MailboxFolderPermission
Shows the Default group (presume this is everyone) only has AvailabilityOnly rights on my calendar. There is one other group who has reviewer rights, but other users not in this group are getting reviewer permissions over my calendar entries.
I also checked the output of: Get-MailboxPermission
Again none of these users are in any of these groups, yet can still review my calendar. I also checked in outlook "calendar permissions", and account settings > delegate access, and again none of these users are listed. Is there anywhere else this could be set? Its very strange.
