    That 503 Service Unavailable error has been reported by many OneDrive users recently, so it is likely related to a temporary issue on Microsoft’s servers that needs to be resolved on their side. You can check if there are any outages or service disruptions reported in your area on the official Microsoft status page:

    In the meantime, some users mentioned that the following steps helped them access OneDrive again:

    clearing the browser cache and site data;

    opening OneDrive in a private/incognito window;

    trying a different web browser;
