In Our ORG, we have kept sharing settings for Case record private, still non-owners can see case records of other users.
How to fix so that only owners or anyone above in Role Hierarchy can see Case records , so far I have checked
1. Sharing Setting is private
2. There is no sharing Rule, for case object
3. There is no View All or View All Records permission granted to the users
4. Non-owner Users have same or Lower role in Role Hierarchy
5. There is no Manual/Apex sharing either
6. There is no Case Team defined in Org
7.Non-owner users neither are account owner for the Case's account.
Please help me to fix it.
