Final update: The email latency issue should be resolved as of 17th March, 7:00 UTC. Please reach out to us if you are not receiving timely auto-shutdown notifications. Thank you for your patience.
Initial Update: We would like to inform the users of DevTest Labs that they may not receive auto VM shutdown notifications via email due to an on-going outage in Azure Email Services since 15th March, 22:42 UTC. The email services team has deployed a fix to mitigate the email latency issue. There could still be delays of upwards of 30 minutes. They will provide us with the next update on 16th March, 18:00 UTC.
In the mean time, please use the Lab Webhook feature in order to receive timely auto shutdown notifications. Please refer to the documentation on how to setup Webhooks here.
We regret the inconvenience this may have caused you and thank you for your patience.
