OneDrive Not Connecting

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:

1. Select the OneDrive cloud icon in the notification area.
2. If it is gray or crossed out, select it and sign in at Set up OneDrive.
3. Confirm that the account is the one where the files are stored—personal Microsoft accounts and work/school accounts are separate.
4. Open Start, search for OneDrive, and launch it again. Microsoft recommends restarting OneDrive when it reports that it is not connected.^2^
5. 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.
