I currently have several Excel VBA macros that open the desktop Outlook application, download specific files from received emails in certain email accounts, perform operations, and send an email back.

I would like to improve this process by scheduling these macros to run automatically using Power Automate. The Power Automate flow should also download some Excel files from a website before running the macro.

From my research, I understand that I would need to acquire a Power Automate Premium license to schedule the execution of these flows through the Windows Task Scheduler. However, my problem is that I would like to be able to run these flows without the need for the Windows session to be logged in. From what I've read and tested, it seems that Excel macros cannot be executed without the Windows session being logged in.

Is there a solution for this issue with Powe Automate Premium? Do I need a Power Automate Process license to execute flows in unattended mode? Will macros that interact with desktop applications work in this mode?

Thanks in advance. Best regards.
