We are experiencing an issue with Microsoft 365 email services today.

Our company website has an online loan application process that requires an automated verification email to be successfully delivered to our TCC email address before applicants can proceed to the loan application screen.

Currently, the verification email does not appear to be reaching the recipient mailbox, preventing applicants from proceeding with their loan applications.

Please investigate and confirm:

Is there any ongoing Microsoft 365 email service disruption?

Are there any email delivery delays or failures affecting our tenant?

Can you identify why the automated verification emails are not being delivered?

What is the expected time for service restoration?

This issue is affecting our members' ability to submit online loan applications. We would appreciate your urgent assistance in resolving it.

Thank you.

    Hello Senthil Murugan,

    The issue with emails in Outlook is directly linked to an ongoing, widespread Microsoft 365 service outage.

    According to Microsoft's official notification (Incident ID: MO1550821), users across multiple regions are currently unable to access their mailboxes or experience email delivery delays in Outlook desktop (MAPI), Outlook on the web, and Exchange ActiveSync due to a service degradation affecting Exchange Online and several connected Microsoft 365 services.

    Latest Status & Mitigation Progress:

    Cause & Action: Microsoft engineers identified that a core connection process on the backend servers became overwhelmed. They are actively taking a measured approach to repair and stabilize the affected infrastructure while balancing traffic to restore full email flow safely.

    Security Confirmation: Microsoft has confirmed that there is no indication of any malicious activity causing this incident.

    Current Status: Classified as Service Degradation. Microsoft is treating this with top priority and releasing continuous updates until full resolution is achieved.

    If you have Microsoft 365 administrator privileges, please sign in to the Microsoft 365 Admin Center to view the latest technical updates:

    • 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 you are a regular user, please reach out to your organization's IT administrator so they can monitor the progress for you. If you 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

    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 closely and let you know here as soon as Microsoft releases the next update
