The Sharing and Permissions settings in Outlook control access to your mailbox and calendar. These permission settings are accessed through the full Outlook client (installed as part of Microsoft Office).
To control access to your whole mailbox, select the Mail tab in Outlook, right-click your email account from the side bar on the left side of the window, and select Sharing and permissions. Click the plus symbol () to add a new user, then select the user whose permissions level you’d like to change, then set the Permission level from the drop-down menu there according to the desired level of access as described below.
To control access to just your calendar, select the Calendar tab in Outlook, right-click your calendar from the side bar on the left side of the window, and select Sharing and permissions. Use the Search bar to add a new user, and then use the drop-down menu to the right of their name to set their level of access. The modern Outlook calendar uses descriptive names for the various levels that don’t match the information below.
