"User content migrated" Error when Creating OneDrive Webhook Subscription
Dear Microsoft Community, Our application is encountering an undocumented error when attempting to set up a Webhook Subscription to a OneDrive app-root folder (/drive/special/approot). This issue began approximately one day after deployment, following an initial period where the subscription process worked correctly, and has now persisted for several weeks. Here's the full error message: { "error": { "code": "ExtensionError", "message": "Operation: Create; Exception: [Status Code: ServiceUnavailable; Reason: User content migrated. Cannot access disabled item.]", "innerError": { "date": "2025-06-10T10:58:15", "request-id": "edff6dc0-45b7-4e7c-8797-3134ebc6bae4", "client-request-id": "edff6dc0-45b7-4e7c-8797-3134ebc6bae4" } } } Could this error be related to: - The absence of an MPN ID? - The type of Microsoft account used for app registration (personal vs. work account)? Any insights or suggestions would be greatly appreciated!
