Hi Melvin,
Thanks, I appreciate the feedback!
Since Power Automate does not directly have a connector to run scripts on an on-prem environment, in this case, an Exchange server, an approach would be to use Azure Automation with a Hybrid Worker to deploy a runbook that can run any exchange command when triggered on Power Automate. It will likely be the same setup as in the article except you're switching local AD for an on-prem exchange server.
