Permissions allow you to give people access to your calendar. Depending on your Outlook client version, you may see different settings.
To assign permissions to your calendar, see Sharing Your Microsoft 365 Calendar for more information.

This option is not recommended if others need to schedule meetings with you.
NOTE: These steps do not prevent someone from tentatively inviting you to a meeting.
- Click on Calendar
- Choose Tools | Options | Calendar Options | Free/Busy Options.
- Click on the Other Free/Busy button
- Set 'Publish = 0 month(s) of Calendar free/busy information on the server'.
- Click OK.
To set this on a resource calendar (e.g., conference room), the resource owner must first sign onto the resource and then follow the steps above.
Note: People given rights/permissions to your calendar can still see it but they cannot do a Free/Busy search against it. If there are already appointments on your calendar before these settings are changed, those appointments will still be searchable (i.e., entries added after the change will not be searchable).
Resource permissions in Outlook for Windows "New" Monarch, Outlook for Mac "New" and Outlook on the web cannot be seen when you view them your own account. They need to be opened in a new profile or in Outlook on the web (open another mailbox option).
Outlook for Windows "old" can still see and edit the permissions.
