The All-Accounts view, also known as Unified Inbox, lets you see emails from multiple accounts in a single inbox view in the new Outlook for Windows, without merging your mailboxes. Each account's inbox stays separate; the view brings them together so you can triage in one place. Users can read, delete, move, archive, and mark messages across accounts without switching between mailboxes.
