In Office 365, under User Profile - My Site Settings, enabled My Site Secondary Admin account and assigned a service account so that using that account, we can update one drive settings of other users in the company.
Using the service account, we can access the following url. However, not able to get the full control.
Also when we try to access the below URL, it says access denied.
The purpose is to customize one driver permission using the service account for all users in the company. How to achieve this ?
