Delegate OneDrive access on Microsoft 365
The Graph API access keys allow access to the OneDrive service for the admin.
In order to access a user's drive, an additional step has to be performed to delegate access to the admin id for which the Graph API access key has been generated.
This has to be done for all users whose data needs to be exported or for all users where data has to be uploaded.
NOTE: The admin ID must have a valid license - a basic license is sufficient. (License application takes about an hour to come into effect)
