Do you know when Microsoft 365 will be fixed? I need to work on my books through Spreadsheets and Word. Please let me know when I will be able to use my programs? Thank you.

    A public restoration estimate specifically for Word or Excel cannot currently be verified; monitor Microsoft’s public service-status page for the latest recovery information.

    Check the current status

    Because Microsoft 365 Home users normally cannot access the business admin dashboard:

    1. Open the Microsoft service-status page.
    2. Look for an active Microsoft 365 incident and any estimated recovery time.
    3. You can also follow @MSFT365status for updates on certain incidents.

    For work or school accounts, an administrator can open Microsoft 365 admin center → Health → Service health, select the active incident, and review its status and update history. Microsoft posts investigation, mitigation, and restoration updates there.^1^

    Continue working in Word and Excel

    If the desktop applications are already installed:

    1. Open Start and search for Word or Excel rather than opening them through a browser.
    2. Open files stored locally on the PC.
    3. Save changes locally until the affected online service recovers.

    Cloud-only OneDrive files may remain unavailable until OneDrive synchronization or the affected service is restored.

    If Word or Excel is not installed, and the Microsoft 365 subscription includes desktop applications:

    1. Go to Microsoft account Services.
    2. Sign in with the Microsoft account used to purchase Microsoft 365.
    3. Find the subscription and select Install apps.
    4. After installation, launch Word or Excel from the Windows Start menu.^2^

    Avoid reinstalling or repairing Office merely because online services are unavailable. If the status page shows no incident and the desktop applications also fail to open, use Microsoft’s recent Office issues page to identify an application-specific problem or contact Microsoft support.^3^

    Welcome to Microsoft Q&A!

    Hello,

    What you are experiencing is currently linked to an active Microsoft 365 service incident tracked under ID EX1550543.

    Microsoft initially reported intermittent connectivity issues affecting Exchange Online mailboxes in the Americas, and has since updated the advisory to confirm that the issue may impact general Microsoft 365 service connectivity across any region.

    What this means for your environment:

    • Affected Services: Primarily Exchange Online / Outlook (desktop client, Outlook on the web, and mobile apps), along with potential authentication or connection timeouts across broader Microsoft 365 services (such as Teams, SharePoint/OneDrive, or the Microsoft 365 Admin Center) that rely on shared front-end connectivity infrastructure.

    Action Required: No configuration changes are needed on your tenant or client devices. Microsoft engineering teams are actively working on mitigation.

    How to track live status:

    Open the Microsoft 365 Admin Center using a Global Admin or Service Support Admin account.

    Navigate to Health > Service health.

    Search for incident ID EX1550543 for real-time mitigation progress and root cause updates.(You can also follow official updates via @MSFT365Status on X).
