    Welcome to Microsoft Q&A!

    Hello,

    What you are experiencing is probably 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).

    Repair the Copilot app from Windows Settings first; if Repair does not restore launching, use Reset and then reinstall only if needed.

    1. Repair or reset Copilot

    Windows 11

    1. Open Start → Settings → Apps → Installed apps.
    2. Find Copilot, select the … menu, then Advanced options.
    3. Select Terminate if shown, and try opening Copilot again.
    4. If it still does nothing, return to Advanced options and select Repair.
    5. If Repair fails, select Reset.

    Windows 10

    1. Open Start → Settings → Apps → Apps & features.
    2. Select Copilot → Advanced options.
    3. Select Repair; if that does not work, select Reset.

    Windows documents Repair as the non-reinstallation option, followed by Reset when Repair is unavailable or ineffective.^1^ The same sequence has resolved matching reports where the Windows Copilot app stopped responding.^2^

    After each action, launch Copilot from Start, rather than the existing taskbar icon, and verify that its window opens.

    2. Check whether the problem is limited to the app

    Open copilot.microsoft.com in a private browser window and sign in.

    • Web Copilot works: the account and service are reachable; continue with the app steps below.
    • Web Copilot also fails: run the connectivity troubleshooter before reinstalling.

    Microsoft also documents launching the installed app from Start, the taskbar, the Copilot key, or Windows key + C.^3^

    3. Run the Copilot connectivity troubleshooter

    1. Open Start, search for Get Help, and open it.
    2. Search for Copilot connectivity troubleshooter.
    3. Run the troubleshooter and apply its recommendations.
    4. Retry Copilot.

    This checks for firewall rules and other connection blockers.^4^

    4. Reinstall Copilot if Repair and Reset fail

    1. Go to Settings → Apps → Installed apps
      — or Apps & features on Windows 10.
    2. Select Copilot → Uninstall.
    3. Restart Windows.
    4. Open Microsoft Store, search for Microsoft Copilot, and install it.
    5. Launch it from Start and sign in before pinning it back to the taskbar.

    The Microsoft Copilot app can be downloaded from Microsoft Store if it is missing or must be reinstalled.^3^

    If the freshly installed app still does nothing, press Windows key + F to open Feedback Hub and report the failure. Include when it began, the Windows version, and a screenshot if possible.^2^
