What it does

This policy setting controls the level of calendar details that Outlook users can publish to the Microsoft Outlook Calendar Sharing Service. If you enable this policy setting, you can choose from three levels of detail: * All options are available - This level of detail is the default configuration. * Disables 'Full details' * Disables 'Full details' and 'Limited details' If you disable or do not configure this policy setting, Outlook users can share their calendars with selected others by publishing them to the Microsoft Outlook Calendar Sharing Service. Users can choose from three levels of detail: * Availability only - Authorized visitors will see the user's time marked as Free, Busy, Tentative, or Out of Office, but will not be able to see the subjects or details of calendar items. * Limited details - Authorized visitors can see the user's availability and the subjects of calendar items only. They will not be able to view the details of calendar items. Optionally, users can allow visitors to see the existence of private items. * Full details - Authorized visitors can see the full details of calendar items. Optionally, users can allow visitors to see the existence of private items.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
