I have cases that are visible to a community user, the sharing reason says Account Sharing. I look at the Account and there is no sharing entry for that user, plus I see no groups or roles that the community user falls into. I have recalculated both Account and Case sharing.
The contact associated with the user is not a contact for any cases on the account and the contact belongs to a different account. (It used to belong to the same account as all the cases, but that was changed recently.)
Any ideas how I can find the reason this user can see these cases?
Edit: I should add that this is a Customer Community Plus User
