Purpose
This article provides information on enabling extended SMTP email logging, which is necessary when investigating issues with Veeam ONE emails, such as missed alarm notifications, unexpected email content, or other email-related problems. SMTP logging is not enabled by default and must be enabled temporarily to collect diagnostic information that can help identify potential SMTP communication issues.
Before proceeding with further steps, please ensure that the SMTP server settings have been correctly configured within the Veeam ONE settings.
Solution
Beginning with Veeam ONE version 12, the registry value to enable extended SMTP logging and the location for email logging have been changed.
If you are still using Veeam ONE version 11a or an older version, the legacy SMTP log collection steps can be found at the end of this article.
