If you are trying to log into Karbon using your Office 365 account and receive this message, your administrator needs to grant you permission to get access.
To resolve this, an administrator will need to:
- Login into the Azure Portal (https://portal.azure.com/)
- Click on Azure Active Directory
- Click Users
- Click User Settings
- Click Yes under App registrations
The user should now be able to login to Karbon without the error above being displayed.
