The inbox told everyone "No role mailboxes connected" and sent them to System Settings, even on a site with a connected mailbox and dozens of conversations. The usual cause is the person holding no committee role, often because the role still points at a member record that was later deleted.

Each links to the place that fixes it, and the last one now goes to Mail Settings, Inbox.
