    Hi Kevin Lynch,

    I’m sorry to hear that you are having trouble with the Microsoft service.

    Microsoft is currently reporting a global outage affecting some of its services. Since Copilot relies on online services to load, it may be related to what you are seeing, although this cannot be confirmed from your description alone. You can monitor the current status here: Service Health Status.

    Please note that this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, cannot directly intervene in Microsoft product features or access back-end systems. My role is limited to providing technical guidance on reported issues, requests, or ideas. As such, I do not have any information regarding the expected resolution time, but I sincerely hope the service will be restored soon.

    Thank you so much for your understanding.

    Reinstall the free new Outlook for Windows from Microsoft Store; you do not need to reinstall the Microsoft 365 desktop suite.

    Reinstall new Outlook

    1. Open Start and select Microsoft Store.
    2. Search for Outlook for Windows.
    3. Select the app published by Microsoft Corporation.
    4. Select Get or Install. If the button says Open, Outlook is already installed.
    5. Open Outlook and follow the prompts to add your email account if it is not restored automatically. ^1^

    New Outlook requires Windows 10 version 1809 (build 17763) or later and an internet connection. ^2^

    Microsoft 365 Basic is not the package used to reinstall this app: new Outlook is a separate Windows Store app, rather than classic Outlook installed as part of an Office desktop suite. ^3^

    If Microsoft Store installation fails

    Open Windows Terminal:

    1. Press Windows+X.
    2. Select Terminal.
    3. Run:
    winget install -i -e --id=9NRX63209R7B --source=msstore --accept-package-agreements

    This installs the Microsoft Store version of new Outlook. ^4^

    After installation, search the Start menu for Outlook (new), launch it, and sign in with the email account you want to use.
