    A 503 “Service Unavailable” error means the service is temporarily unavailable or not ready to handle the request.

    For OneDrive and Microsoft 365, this typically indicates a temporary service-side issue or throttling. Recommended actions:

    1. Wait and retry after some time. A 503 is often transient and may clear automatically.
    2. If multiple users are affected or the issue persists, check the Microsoft 365 Service Health Dashboard from the Microsoft 365 admin center to see if there is an ongoing OneDrive or Microsoft account incident.
    3. If using OneDrive APIs or automation, implement retry logic with a delay when receiving HTTP 503 responses. The response may include a Retry-After header that indicates how long to wait before retrying.

    If the problem continues for an extended period and no service incident is reported, contact Microsoft Support for further investigation.

    Many users have reported running into this issue. It seems to happen when multiple different accounts are used to sign in to OneDrive or Microsoft services in the same browser session. For example, this can occur if one account is signed in to Edge, while another account is also signed in through a different Edge tab or an InPrivate window.

    To avoid this, try keeping each account in a separate browser. For example, use Edge for one account and Google Chrome for another. This helps prevent account session conflicts and may stop the error from appearing.
