Which mailboxes does Monty support?

Gmail and Google Workspace today, connected through Google's official OAuth consent flow — never your password. Monty sends from your real address through your own mailbox, never a relay domain, so your reply arrives from the person your lead already knows. Microsoft Outlook and Microsoft 365 / Exchange Online support is built but not switched on yet, and self-hosted/on-prem Exchange and plain IMAP mailboxes aren't supported; contact us if any of those is a blocker and we'll tell you honestly where it sits on the roadmap.
