Hi Padma,

I’m sorry you’ve been unable to access Outlook since 4 AM. I understand how disruptive this is, especially when you need your email for work. I don’t have a confirmed restoration time to share based on the incident update available to me.

I would like to share an update regarding the connectivity issue affecting multiple Microsoft 365 services.

According to Microsoft’s notification (Incident ID: MO1550821), users may be unable to connect to or access multiple Microsoft 365 services, including Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot, and Microsoft Defender XDR.

The update shared with us indicates that Microsoft identified elevated load across multiple regions and was restarting and repairing affected infrastructure to restore capacity.

As the forum’s AI recommended, please ask your organization’s IT administrator to check Health > Service health in the Microsoft 365 admin center and open incident MO1550821. This will help confirm whether your organization is affected and provide the latest recovery updates, including an estimated restoration time if Microsoft provides one.

If the admin center is also inaccessible, you can check through this link.

Please note that a “next update” time in the incident notice is the time of the next progress report, rather than a guaranteed time for service restoration.

Answer 2

The repair time cannot be confirmed publicly; your Microsoft 365 administrator should check Admin center → Health → Service health → Exchange Online/Outlook for the incident status, latest update, and any restoration estimate.

Check the current incident

Sign in to the Microsoft 365 admin center with an admin account.
Open Health → Service health.
Under Active issues Microsoft is working on, look for Exchange Online or Outlook.
Open the incident to view:
- User impact
- Current status
- Last update
- Microsoft’s mitigation progress and restoration estimate, if provided

Microsoft posts updates there while investigating and restoring service. If the admin center itself is inaccessible, use Microsoft’s public service-status page referenced in the same documentation. Service Support Admin and Helpdesk Admin roles can also view service health.^1^

If you are not an administrator, ask your organization’s IT team to check the incident for your tenant. A precise completion time should not be assumed unless it appears in that incident’s updates.

Determine whether it is local

Try signing in through Outlook on the web:

Web and desktop both fail, especially for multiple employees: treat it as a possible Microsoft 365 or organizational account incident and follow Service health.
Web works but classic Outlook fails only on this PC: run the authentication troubleshooter:
1. Close Outlook.
2. Open the Windows Get Help app.
3. Search for Outlook password problem.
4. Run the suggested checks and reopen Outlook.

For intermittent connection failures, use the classic Outlook connectivity troubleshooter instead. These tools require Windows 10 or later, must run on the affected PC, and do not apply to new Outlook for Windows.^2^

Microsoft also maintains a current list of fixes and workarounds for known classic Outlook issues.^3^

If no incident is listed but several users are affected, an administrator can select Report an issue on the Service health page. If only one account fails, provide IT with the exact error message, whether Outlook on the web works, and the Get Help results.
