CANNOT LOG IN

Hi @Lidie McCarthy ,

According to Microsoft's notification, users may be unable to connect to or access multiple Microsoft 365 services, including Outlook, Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot, and Microsoft Defender XDR, among other services.

Microsoft has identified infrastructure stability issues affecting traffic flow across multiple regions. As a result, users may experience connectivity failures, delayed email delivery, and intermittent issues accessing various Microsoft 365 features and services. Services and features that rely on Exchange Online are particularly impacted, while functionalities that do not depend on Exchange Online may remain operational.

According to the latest update, Microsoft is actively working to improve infrastructure stability and restore service availability. Although partial recovery has been observed in some regions, the issue has not yet been fully resolved, and Microsoft is continuing to investigate additional mitigation measures.

If you have Microsoft 365 administrator privileges, please sign in to the Microsoft 365 Admin Center to view the details of this issue.

If you're not an admin and don't know who the admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support

Ask your admin to follow these steps:

• 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.

If admin center is currently not available, you can check the status of this issue at https://status.cloud.microsoft/ .

I'll continue to monitor this case and share further updates as soon as they become available.

Kind regards.
