What it does

When Storage Sense runs, it can dehydrate cloud-backed content that hasn’t been opened in a certain amount of days. If the group policy "Allow Storage Sense" is disabled, then this policy does not have any effect. Enabled: You must provide the minimum number of days a cloud-backed file can remain unopened before Storage Sense dehydrates it from the sync root. Supported values are: 0 - 365. If you set this value to zero, Storage Sense will not dehydrate any cloud-backed content. The default value is 0, or never dehydrating cloud-backed content. Disabled or Not Configured: By default, Storage Sense will not dehydrate any cloud-backed content. Users can configure this setting in Storage settings.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.

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.
