@Quattrocchi, Calogero - Thanks for reaching out to us.
This is a known issue. It is a default message that is sent by Azure, even if you are not using Azure DevTest Labs. The message may be a generic message that is sent to all virtual machines that have auto-shutdown and notifications enabled, regardless of whether they are in Azure DevTest Labs or not. Azure Compute leverages DTL's schedule functionality and hence the text states 'Azure DevTest Labs'. We have an item in the backlog to get the text corrected. However, it is not prioritized yet.
Hope this helps. and please feel free to reach out if you have any further questions.
