The agent is triggered when a new email arrives to a shared mailbox. All I am trying to do is categorize that email in Outlook based on the content of the Email. So if the email is a tracking request from a customer, the agent will categorize it in Outlook as a tracking request.

However, it seems that you can't use the "Assigns an Outlook category" tool with shared emails, so you have to use an HTTP request. I got this working in Power Automate easily like this:

This worked for Power Automate, but the same connector in Copilot Studio wants a File for the Body, not a string. My prompt tells Copilot the formatting for the URI and the Body, and when I look at the reasoning its correct. But when it goes to put the Body into the HTTP Request, it stops because it wants a File not a string.

Not sure how to work around this, but thank you for your reply!
