Hey,
New to this community, so any comments on post structure are welcome 
So,
I was using the official Microsoft 365 Email (Outlook) module, and created a new connection to Microsoft - using custom client credentials.
I set up the app in Microsoft and checked it locally using an api call - and succeeded in sending a mail on behalf of the app from a mail account that my personal account doesn’t have permission to but the app has.
Sadly, I couldn’t emulate this behavior in Make. It seems to me that the connector/module tries to use “delegated” permissions and act on behalf of the user instead of using “application” permissions and acting on behalf of the app.
I added an image showing my failure inside Make.
I have two main questions:
- Is there anyone that succeeded? Am I doing something wrong?
- If the behavior is really on behalf of the user - why allow for custom app credentials in the first place?
