I am trying to set my Logic App to fully unattended. I currently have a flow that will send out emails to users including Approvals. They are running from my admin account currently, I need to be able to connect all the connectors to a service principal or managed identity. I was able to connect the items to the Service Principal, but when I try and setup the Manage Identity, User or System, it says:
"Please check your account info and/or permissions and try again. Details: Failed to retrieve token for resource=https://outlook.office365.com. Message=Name cannot be null or empty."
From my research I believe I would need to add the "outlook.office365.com" as a resource, but nothing is pointing to where to do this. All the details show azure resources like KeyVault or Azure Storage, but the Outlook connector doesn't allow Service Principals only Managed Identities. Can anyone help me with this dilemma, it is one of the last items I need to address for this project?
