When deploying a ConfigMgr Cloud Management Gateway to Azure using VM scale sets and you receive the following error in CloudMgr.log:
ERROR: Resource Manager - Deployment operation details: {"value":[{"id":"/subscriptions/xxxxxxxxxxxx/resourceGroups/xxxxxxxx/providers/Microsoft.Resources/deployments/CreateKeyVaultd7fa35f7-7f9a-4a49-b780-2e3d267f29a3/operations/4B42A1CC456C4E8A","operationId":"4B42A1CC456C4E8A","properties":{"provisioningOperation":"Create","provisioningState":"Failed","timestamp":"2022-08-24T09:29:33.5616488Z","duration":"PT0.2383212S","trackingId":"f183ade1-5a45-4cd4-ab63-b3ca7801f48a","statusCode":"Conflict","statusMessage":{"error":{"code":"MissingSubscriptionRegistration","message":"The subscription is not registered to use namespace 'Microsoft.KeyVault'.

You'll need to log on to the Azure portal and perform the following:
1. Find the Azure subscription being used for the CMG and select it
2. Select "Resource Providers" on the left hand side
3. Register "Microsoft.KeyVault", "Microsoft.Compute" & "Microsoft.Network"
4. Within a few seconds the Resource Providers will have been registered.
5. Retry CMG provisioning from ConfigMgr console (delete previous attempt and re-provision.)
