Hi ALEX, As per description, this is not directly related with Power Automate but let me guide you a little here. Basically, It's due to insufficient Dataverse database capacity in your tenant. Creating sandbox environment (with Dataverse) requires minimum of 1GB of available database capacity (tenant level). If your organization has already consumed its allocated capacity, the environment creation will fail. Because you want it for learning and experimenting, I recommend you to try creating a Developer or trial environment (if it is allowed in your Tenant. If not, ask IT team to create one env for you.) and try experimenting there. Here are some references for you:
For Trial Env: https://learn.microsoft.com/en-us/power-platform/admin/trial-environments#create-a-trial-standard-environment-in-the-power-platform-admin-center For Developer Env: https://learn.microsoft.com/en-us/power-platform/developer/create-developer-environment Hope this helps. Please let me know if you facing any further issues. Happy learning :)
