We are trying to test the One Calendar application (installed on Android Device) with Exchange Online.
Our Azure environment is configured with MFA.
But whenever user enters the username & password in One Calendar, the application is getting connected to calendar of the user successfully but it is not prompting for MFA & also there is no sign-in logs as well for the logged in user in Azure AD.
I want to understand how this authentication take place.
Can anyone please advise?
