Sending, receiving, and organizing email in Outlook on the web for business
Public reports indicate that other users are experiencing Microsoft 365 and Outlook login problems around 10:20 AM PST on November 12, 2026, but they do not confirm that Microsoft has declared an Outlook on the web incident affecting every tenant.^1^
Confirm whether your organization is affected
Ask a Microsoft 365 administrator to:
- Sign in to the Microsoft 365 admin center.
- Go to Health → Service health.
- Check Exchange Online and Office on the web under Active issues Microsoft is working on.
- Open any listed incident to review its user impact, affected services, status, and updates.
Service Support administrators and Helpdesk administrators can also view Service health. If an issue is not listed, the administrator can select Report an issue so Microsoft can compare reports across organizations.^2^
If the admin center itself is inaccessible, check Microsoft’s public service-status page at status.cloud.microsoft.^2^
What to do next
- If an incident or advisory is listed: No local reconfiguration is normally useful unless the incident details provide a workaround. Monitor Microsoft’s updates and retry after the status changes to Service restored.
- If several coworkers are affected but nothing is listed: Have an administrator use Report an issue from the Service health page.
- If only your account or device is affected: Try Outlook on the web in a private browser window or on another network/device. If that works, the problem is more likely local to the original browser, session, or network.
- If Outlook on the web fails everywhere only for your account: Contact your organization’s Microsoft 365 administrator so they can check the account, Exchange Online access, and licensing before opening a Microsoft support request.
