Calendar Permissions

This report shows who has been granted access to whose calendar across the selected tenant. It can be read either way round, listing what each user can see or listing who can see each calendar, which makes it a quick way to audit delegated calendars without checking mailboxes one at a time.

Action Buttons

By User / By Calendar

Switches how the report is grouped. By User is the default and gives one row per user with the calendars they can reach. Clicking it changes to By Calendar, which gives one row per calendar with the users who can reach it. The columns change with the grouping.

Table Details

In the By User grouping:

Column	Description
User	The person who has been granted access to one or more calendars.
User Mailbox Type	The kind of mailbox that person has of their own, or Unknown where they have none.
Permissions	The calendars this person can reach. See the note below.

In the By Calendar grouping:

Column	Description
Calendar UPN	The address of the mailbox whose calendar the row describes.
Calendar Display Name	The friendly name of that mailbox.
Calendar Type	The kind of mailbox, for example UserMailbox or SharedMailbox.
Permissions	The users who can reach this calendar. See the note below.

Permissions is a button labelled with the number of entries behind it. Clicking it opens the detail: in the By User grouping that is the calendar, its address, the access rights, and the calendar folder name, and in the By Calendar grouping it is the user, the access rights, and the folder name.

The Default and Anonymous entries that every calendar carries are left out, so a calendar with no explicit delegate does not appear at all. The folder name is worth reading where a mailbox was created in another language, because the calendar folder is named in that language rather than being called Calendar.
