Classic Conditional Access block access to Defender data Connector

Copper Contributor


Has anyone faced issues with the Classic Conditional Access (CA) policy obstructing access to the connector page for Defender 365 in Sentinel? I have encountered a multitude of errors.

It appears that disabling the Classic policy named [Windows Defender ATP] Device policy resolve the issue. However, I'm uncertain about the potential repercussions of this action. Is anyone aware of the implications of disabling this policy? Additionally, there are modern policies in place that encompass all cloud applications – so it should be covered
