    I think they have been a bit successful, more to follow.

    We’re applying infrastructure capacity improvement where possible to help support traffic in regions coming online. We’re continuing to monitor the results of changes applied so we can identify strategic actions that can help to improve service health across all affected regions. More info under EX1550543 and MO1550821 in the Microsoft 365 admin center, as well as https://msft.it/6016xBHGu if the admin center is not available to you.

    Hello @June Wu

    I'm sorry for the inconvenience this issue has caused.

    Multiple users have also reported similar issues accessing their Microsoft 365 mailboxes through both the Outlook desktop application and Outlook on the web.

    This may indicate a service-side issue rather than a problem with your individual account or device.

    Please be patient while Microsoft investigates and works toward resolving the issue.

    If Microsoft publishes any official updates or announcements regarding this incident, I will update you as soon as possible. In the meantime, you can also monitor the Microsoft 365 Service Health dashboard for the latest information:

    https://admin.microsoft.com/#/servicehealth

    Thank you for your understanding and patience.
