Dear Vishnu Anand,
Thank you for contacting Microsoft Q&A Support.
Based on your description, allow me to provide you with the information.
Currently, Microsoft 365 environment only supports alert notifications for Exchange admin role elevation. To enable this, you can follow these steps:
- Sign in to the Microsoft Defender portal: https://security.microsoft.com/ using an account with Admin privileges.
- Navigate to Email & Collaboration → Policies → Alert Policies.
- Locate the alert named "Elevation of Exchange admin privilege".
- Enable the alert to receive notifications when a user is granted Exchange admin permissions.
Important Note: Because Microsoft 365 does not support alert notifications for admin role assignments in other portals (e.g., Teams, SharePoint, Entra ID) currently. So, if this functionality is important to your organization, we kindly recommend you can submit feedback via the Microsoft Feedback Portal - feedbackportal.microsoft.com
Additionally, we would like to recommend limiting the number of Global Administrator in your tenant to a small number (ideally is 2):
- One for regular tenant management tasks.
- One as a backup administrator.
Just because only Global Admins can assign other admin roles, so minimizing this role helps reduce your risk.
About your second requirement, I understand you want to receive notifications when someone is added or removed as an admin or owner of a SharePoint site, but currently, Microsoft 365 does not support alerts for changes to SharePoint site admin or owner roles, instead, you can configure alerts for changes to SharePoint group , which may serve as a partial workaround.
If I misunderstood any part of your request, please feel free to clarify, and I’ll be happy to assist further.
