    Hello @Balcom, Brittney (Consumer Foods Grocery)

    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. At the moment, please help me to follow the next update in Microsoft 365 admin portal if you are an admin by following the instruction:

    • Sign in to the Microsoft 365 Admin Center.
    • Go to Health > Service Health.
    • Search for Issue ID: MO1550821.
    • Select the issue and expand the details to review the latest updates, affected services, impact, and remediation information.

    enter image description here

    Since this is a worldwide incident, the Microsoft product team is doing their best to resolve the issue as soon as possible.

    If you do not have permission to view the incident in the admin center, you can check Microsoft's public service status page for available updates without signing in: https://status.cloud.microsoft/

    I'll continue to monitor this case and let you know if there is any update.

    There is currently no confirmed public time or date for full Outlook restoration in the U.S.; Microsoft is tracking the incident through Microsoft 365 Service health, where any recovery estimate will be posted.

    Check the latest Microsoft update

    • Microsoft 365 business administrator: Sign in to the Microsoft 365 admin center, then select Health → Service health → Active issues Microsoft is working on. Open the Exchange Online/Outlook incident for its latest status, next-update time, and any tenant-specific restoration estimate. Service Support Admin and Helpdesk Admin roles can also view this information.^1^
    • Unable to access the admin center: Check the public Microsoft status page at https://status.cloud.microsoft.
    • Not an administrator: Contact your organization’s IT team and ask for the current Exchange Online incident update from Service health.

    The disruption has been reported as a widespread Microsoft 365/Outlook outage affecting U.S. users, but the available public reporting does not provide a reliable fixed restoration time.^2^

    Avoid reinstalling Outlook or changing profiles while Service health shows an active Exchange Online incident. If Microsoft marks the incident resolved but Classic Outlook remains disconnected, first test Outlook on the web; if web access works, the remaining issue may be local to the Windows client or its account configuration.^3^
