What it does

CcdMaxCacheSizeInMBs specifies the maximum local cache size in megabytes, per user, during normal operation. Normal operation assumes that all Cloud Cache providers are available, and that storage performance is adequate to accept I/O at the rate necessary to accommodate profile utilization. CAUTION: Do not use this setting unless the performance and technical aspects to this setting are fully understood as this setting is a leading cause to poor performance and has limited use cases. Registry Entry: HKLM\SOFTWARE\Policies\FSLogix\ODFC\CcdMaxCacheSizeInMBs Type: DWORD Values: Min (No Limit) = 0, Max = 10000000

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.
