Hi @leo85,
Based on the issue that you mentioned, do you want to inform your Environment Admins once the storage limit is approached?
Could you please share a bit more about the scenario?
Actually, the emails notifications are not configurable at this moment. This is set to receive when the threshold limit is reached.
Additionally, tenant admins will also be notified once their org reaches 15% of available capacity, and once more when their org reaches 5% of available capacity.
So if you want to automatically inform Environment Admins of the capacity used by an Environment they created once the storage limit is approached, I am afraid that there is no way to achieve this in PowerApps.
If you want this feature to be added, please raise an new idea in our idea forum:
Power Apps Ideas - Power Platform Community (microsoft.com)
Hope it could help you.
Regards,
Qi
