First-Party Email & Calendar

Current State​

Today SynergyOS ships an email and calendar client that connects to Microsoft 365 Exchange. Exchange handles sending/receiving; SynergyOS manages the UI, organization in the unified folder tree, and attachment handling.

What We Are Considering​

Build a native SynergyOS email and calendar backend service so mail, events, files, and tasks live in one system with one permission model.

Highlights we are evaluating​

  • Mailboxes, domains, aliases, groups managed in SynergyOS Admin.
  • SMTP submission and inbound mail with DKIM, SPF, DMARC and anti-spam/phishing quarantine.
  • Calendars with invites, shared calendars, resource booking, ICS import/export, and time-zone smart scheduling.
  • Unified storage model: messages, threads, attachments, and events are first-class “items” in the same folder tree as files and notes.
  • Rules & automation: server-side rules, webhooks, and agents to route messages, extract data, and auto-file attachments.
  • Advanced search & retention: metadata, tagging, legal hold, journaling, and configurable retention policies.
  • Interoperability: gateways for IMAP/SMTP and Microsoft Graph to ease migration or hybrid setups.
  • Deliverability controls: per-domain sending limits, feedback loops, and bounce analytics.
  • Regional deployment: keep data in-region to meet residency requirements.

Why It Matters​

  • One permission model across email, files, notes, and calendars.
  • Lower friction: file emails and attachments directly into project folders, no duplication.
  • Reliability & latency improvements for workflows that span apps.
  • Compliance by design: consistent retention, auditability, and org-wide policies.

Risks & Trade-offs​

  • Running mail at scale requires 24×7 operations, deliverability tuning, and constant anti-abuse work.
  • Some M365 enterprise features may not exist on day one; hybrid mode mitigates this.
  • Migration from legacy mailboxes needs careful planning for archives and aliases.
