@Ian Wilderspin Thanks for posting your query on Microsoft Q&A. Please check if there is any service health alert or resource health alert set up with the email of the non-technical member.
There are several ways you can ensure that the emails reach the right person in the team.
Azure Service Health notifies you about Azure service incidents and planned maintenance so you can take action to mitigate downtime. Configure customizable cloud alerts and use your personalized dashboard to analyze health issues, monitor the impact to your cloud resources, get guidance and support, and share details and updates.
Azure Resource Health helps you diagnose and get support for service problems that affect your Azure resources. It reports on the current and past health of your resources.
For more information on the various classes of service health notifications, see Service health notifications properties.
Let me know via comments if you have further questions.
