Third party apps with Conditional Access + On-Premises Exchange

Copper Contributor



I am wondering how conditional access actually works with third party apps when in an on-premises Exchange environment. Microsoft states the only native mail/calendar apps are supported when using on-premises Exchange but we experience a variety of behaviors.


We currently have two users with the same policy sets who are experiencing two direffrent behaviors when using the thrid party calendar app "WeekCal". Both of the users was enrolled and was using WeekCal before we enabled conditional access. As soon as the policy was enabled, the synchronization stopped working only for one of the users. Is it a coincident that the sync was stopped or is this expected behavior?
