    Hello @Gaz

    I understand that currently can send or receive emails all day even using Outlook on laptop or mobile device and I would like to share an update regarding the connectivity issue affecting multiple Microsoft 365 services.

    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. 

    Microsoft has identified that the affected infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors. Microsoft is currently restarting and repairing impacted portions of the infrastructure to restore capacity. Additionally, they are investigating an unexpected increase in a specific type of service traffic and evaluating options to redirect traffic to alternative infrastructure to expedite recovery.

    The incident is currently classified as Service Degradation, and Microsoft is actively investigating and working to mitigate the issue.

    If you have Microsoft 365 administrator privileges, please sign in to the Microsoft 365 Admin Center using this link to view the details of this issue or follow those steps below:

    • 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.

    Latest update from Microsoft product team:

    enter image description here

    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.

    Microsoft is currently reporting an Exchange Online service degradation affecting mailbox access from Outlook on the web, desktop clients, and phones, so do not reset or reconfigure every device while Microsoft is restoring the service.^1^

    Check restoration progress

    If you are a Microsoft 365 administrator:

    1. Sign in to the Microsoft 365 admin center.
    2. Go to Health → Service health.
    3. Open the active Exchange Online incident.
    4. Review User impact, Status, Last updated, and All updates for Microsoft’s latest restoration information.
    5. Select Manage notifications for this issue if you want incident updates sent to an alternative email address.

    Service-health incidents include Microsoft’s investigation and mitigation updates. The current information does not provide a dependable completion time; the incident record is the authoritative place to monitor progress.^2^

    If the admin center is inaccessible, continue checking the public Microsoft service status page.

    What to do now

    • Do not delete Outlook profiles, remove accounts, change passwords, or reinstall Outlook. An organization-wide failure across web, laptops, and phones is consistent with the reported service incident rather than an isolated client configuration problem.
    • Tell users that email access and delivery may remain unavailable or delayed until Microsoft completes mitigation.
    • Use another communication channel for urgent business messages.
    • After Microsoft marks the incident Service restored, test Outlook on the web first, then desktop and mobile clients.

    If your tenant remains affected afterward

    If the incident is marked resolved but your users still cannot connect:

    1. In Health → Service health, select Report an issue and submit the tenant-specific symptoms. Microsoft uses those reports to determine whether an additional incident exists.^2^
    2. Run Diag: Troubleshoot Email Delivery from the Microsoft 365 admin center for affected sender and recipient addresses. This requires a Microsoft 365 administrator account and is not available in certain sovereign cloud environments.^3^
    3. Open a Microsoft 365 support request and reference the Exchange Online incident, affected users, failure start time, and whether Outlook on the web is still failing.

    Billing or price concerns are separate from outage restoration; raise those through your Microsoft 365 billing partner or an admin-center support request after documenting the duration and business impact.
