Looks like Basic Authentication with api v1.0 is the problem.

I have the same behavior with API v2.0 Do you have any idea how to solve the problem?

I changed my script to use EWS for now until I can figure out how to use OAuth and Graph.

v1.0 "Basic Authentication for Outlook REST API is no longer supported" (403) Forbidden v2.0 "Authentication for this API version requires OAuth." (403) Forbidden

How do we fix this?

With this article I'm able to get the AuthToken, but my knowledge is not enough to get it work with the Invoke-RestMethod. May one of you can figure out how.
