OneDrive is part of Microsoft 365, but a problem with one Microsoft 365 service does not necessarily mean OneDrive is also down; check whether the reported incident specifically lists OneDrive or SharePoint Online as affected.
Check for an outage first
- Work or school account: Ask your Microsoft 365 administrator to open the Microsoft 365 admin center → Health → Service health. The administrator can see active incidents, affected services, user impact, and recovery updates. Service Support and Helpdesk administrators can also view this page.^1^
- If the admin center cannot be reached: Check Microsoft’s public service-status page at https://status.cloud.microsoft.
- Personal Microsoft account: Check the OneDrive service status at https://portal.office.com/servicestatus, as directed by Microsoft’s OneDrive sign-in guidance.^2^
If an active incident lists OneDrive or SharePoint Online, local repair steps generally will not resolve it; monitor the incident until Microsoft reports that service is restored.
If no OneDrive incident is listed
On Windows:
- Select the OneDrive cloud icon in the notification area.
- If it is gray or crossed out, select it and sign in at Set up OneDrive.
- Confirm that the account is the one where the files are stored—personal Microsoft accounts and work/school accounts are separate.
- Open Start, search for OneDrive, and launch it again. Microsoft recommends restarting OneDrive when it reports that it is not connected.^2^
- If it still cannot connect, temporarily test through a mobile hotspot. If that works, a firewall, VPN, proxy, internet provider, or organizational network policy may be blocking access. Microsoft also recommends checking that OneDrive is current before investigating those network controls.^3^
For a work or school account, contact the organization’s IT administrator if service health is normal but sign-in still fails. For a personal account, use Contact Microsoft Support from OneDrive support if the problem continues.
