Instant Search is not working for some users, specifically, the All Mailbox search returns no results. This only affects users who don’t use the conversation view. If you use the conversation view (Show as Conversation), All Mailbox search works "as expected".

To group by conversations, switch to the View tab and tick Show as Conversations.
With Show as Conversations enabled, the All Mailbox search scope works.
