    Hi Sheila

    Thank you for reaching out.

    Based on my research, Microsoft has officially posted an active service degradation advisory in the Microsoft 365 admin center regarding this outage (tracked under incident ID MO1550821). They are currently investigating a widespread service degradation preventing users from connecting to multiple Microsoft 365 services, including Exchange Online and Outlook on the web.

    Currently, Microsoft is actively investigating the issue on their end, so there is no action needed from end users at this time.

    In the meantime, please ask your IT administrator to monitor MO1550821 under Health > Service health for further updates. Having them use the "Report a problem" feature will also help Microsoft log the impact on your organization's tenant.

    In case you do not know who your IT admin is, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support  

    I hope the information I shared earlier was somewhat helpful in addressing your issue. Hope they deploy a fix soon.

    Microsoft is currently reporting a Microsoft 365 service degradation affecting connections to multiple services, but it has not published a restoration time yet.^1^

    What to do now

    1. Monitor Microsoft’s public service-health page for recovery updates and any estimated resolution time.^1^
    2. Try Outlook on the web in a browser. If it works, use it temporarily while Classic Outlook is disconnected. If it also fails, that is consistent with the broader Microsoft 365 incident.
    3. If this is a managed work account, ask your Microsoft 365 administrator to check Microsoft 365 admin center → Health → Service health for tenant-specific details.

    Avoid removing the account, rebuilding the Outlook profile, or reinstalling Office while the service incident remains active; those local changes will not resolve a Microsoft-side outage.

    If Classic Outlook remains disconnected after Microsoft reports recovery

    • Look at the status bar at the bottom of Outlook.
    • If it says Working Offline, select Send/Receive → Work Offline. The button should no longer be highlighted, and the status should change to connected.^2^
    • If it says Disconnected or Trying to connect, run the Classic Outlook connectivity troubleshooter through Microsoft’s Get Help app. This requires Windows 10 or later and must be run on the affected PC; it does not apply to new Outlook.^3^
