Exchange Server by Postgate AI

Exchange Server by Postgate AI connects Claude to Microsoft Exchange mailboxes - including Microsoft Exchange Server SE, 2019 and 2016 on-premises and hybrid environments that no other AI connector reaches. 70 tools cover mail (read, search, drafts, send), calendar (appointments, availability, meeting scheduling, rooms), contacts, tasks, folders, attachments with PDF/DOCX/XLSX extraction, out-of-office, server-side inbox rules, mailbox statistics, and one-call briefing and meeting-preparation compounds. Built for teams: every user authenticates individually via OAuth 2.0/PKCE and works with their existing Exchange permissions - no service account, no application impersonation. Credentials are stored RSA-4096-encrypted in a per-user vault. Connected via EWS to Exchange Server SE, 2019 and 2016, on-premises and hybrid. Operated in Germany under a GDPR data processing agreement; message content is neither stored nor logged.
