You might encounter scenarios where you cannot grant consent to certain applications. This will occur when an application requires permissions that only an administrator can approve. In these cases, you can request admin consent through the built-in Microsoft 365 workflow.
Admin consent is needed when an application requests permissions that allow it to access sensitive information or perform actions on behalf of users across the organization. To protect data and ensure security, only tenant administrators can grant these permissions.
If you see a message stating "Need admin approval" when trying to use an application, it means the app requires permissions beyond what you can approve.
On the consent request screen, click on the “Request approval” button. A request will be sent to members of the Enterprise App Reviewers group.
You may be asked to provide a reason for why you need access to this application.
The admin team will review your request and, if approved, grant the necessary consent. You will receive a notification once the consent has been granted.
Once an admin has granted consent, you can try accessing the application again.
