We are getting the following error when enabling the PowerPoint integration:
AADSTS50011: The redirect URI 'https://omexexternal-prod.westeurope.cloudapp.azure.com/landing' specified in the request does not match the redirect URIs configured for the application '3f520182-023f-4483-8cc1-acb6b6c64280'. Make sure the redirect URI sent in the request matches one added to your application in the Azure portal. Navigate to https://aka.ms/redirectUriMismatchError to learn more about how to fix this.
What are we doing wrong?
