UserNeeds changes for IntuneL_ShortenEventsType

Supported on SUPPORTED_Windows7 (defined in the Windows templates)

5568.1000

What it does

This policy setting allows you to shorten the default duration of appointments and meetings by a specified number of minutes. If you enable this policy setting, you can choose between the following options: End Early, Start Late, None. If you select End Early, meetings and appointments will end early by the specified number of minutes. If you select Start Late, meetings and appointments will start late by the specified number of minutes. If you select None, the default meeting duration will not be shortened. In all cases, the settings for this feature will be disabled in the Outlook Options dialog. If you don’t configure this policy setting, users can modify these settings by going to File > Options > Calendar. Note: This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise.

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.
