Outlook combines mail with the Microsoft work stack. Brev concentrates on personal mail, local search, offline continuity and a native Mac workflow. It does not reproduce Exchange administration, Teams, add-ins or corporate policy controls.

The mailbox mirror powers both the graphical app and the Brev CLI.
Microsoft 365, Exchange workflows and Windows are outside the current preview.
