    If SCOM 2025 is not sending alert notifications using SMTP, here are some troubleshooting steps you can take:

    1. Check SMTP Configuration: Ensure that the SMTP server information is correctly configured in SCOM. This includes the Fully Qualified Domain Name (FQDN), port number, and authentication method. You can refer to the configuration steps in the SCOM documentation to verify this.
    2. Verify Email Channel Setup: Make sure that the email notification channel is properly set up in SCOM. This includes ensuring that the channel is enabled and that the return email address is correctly specified.
    3. Event Viewer Logs: Check the event viewer logs for any errors related to the notification system. Each time the notification part runs, it logs events into the event viewer, which can help identify issues.
    4. Test SMTP Server: Use the test SMTP server functionality in SCOM to send a test email. This can help confirm whether the SMTP server is reachable and configured correctly.
    5. Firewall and Network Configuration: Double-check that there are no firewall rules or network configurations that might be blocking the SMTP traffic, even if the ports are opened and IPs whitelisted.
    6. Retry Interval: If you have configured a retry interval, ensure that it is set appropriately. This is relevant if you have a secondary SMTP server configured.
    7. Permissions: Ensure that the account used for SMTP authentication has the necessary permissions to send emails.

    If you have gone through these steps and the issue persists, you may want to consult the SCOM documentation for further details on configuring email notifications or consider reaching out to Microsoft support for assistance.
