12.4 A Caution Regarding the Re-sharing Feature

Use caution when enabling file re-sharing. Removing one user's access rights to an item does not remove the access rights of other users with whom the item was re-shared.

For example, suppose User A shares an item with User B and grants re-share rights. User B then shares the file with User C. Even if User A revokes User B's access rights to the item, User C continues to have access to the shared item.
