Veeam Backup for Office 365 No E-Mail Notification After Job Run

Veeam Backup for Microsoft Office 365
Last Modified:


When the backup job completes the Job notification is never received.


  1. Error: Unable to connect to the remote server
  2. Job completes with no Error, but you do not receive a notification email.  This can be caused by:
    • Email relay server blocking emails that exceed 512KB size
    • The email is being blocked by the email filter
  3. Email Notifications are configured incorrectly


Solution 1

  • When Veeam sends the E-mail for job completion it is sent from the proxy that is configured in the job. The test email will only check the connection from the Veeam Office 365 server to the SMTP and not the proxy.  Ensure that the Proxy chosen in the Job settings has access to the SMTP server.

Solution 2

  • When Veeam Office 365 connects with the SMTP server to send the mail but we do not wait for a confirmation that the email was sent. If this message was rejected for any reason there will be no error from our console.  Check email relay settings and spam filter for quarantined email around the time the job completes
