Inboxed vs. Outlook
Outlook is the enterprise default. But on Mac, it's a resource-heavy port packed with features you don't need. Inboxed is purpose-built for macOS.
| Feature | Outlook | Inboxed |
|---|---|---|
| AI Processing | ✕ Microsoft Copilot (Cloud) | ✓ Local LLM (Apple MLX) |
| Privacy | ✕ Microsoft cloud sync | ⊕ 100% On-Device |
| Cost | $99/year (M365) | ⚡ Free (Pro: $1 lifetime) |
| Performance | ✕ Heavy / Bloated | ⊙ Ultra-light (Rust + Tauri) |
| Platform | Cross-platform port | ✓ Native macOS |
| Subscription | ✕ Required | ✓ None needed |
Escape the subscription trap.
Outlook wants a $99/year Microsoft 365 subscription for full features. And your emails pass through Microsoft's servers for AI processing.
Inboxed costs nothing to use, runs natively on macOS, and keeps every email AI interaction on your device.
Bottom Line
Microsoft Outlook in 2026 is a significantly different product than the Outlook of five years ago: it now includes Copilot AI for email drafting and inbox management, has a more modern interface, and works across Windows, macOS, iOS, and Android. For organizations running Microsoft 365, it's the natural center of a tightly integrated suite covering email, calendar, Teams, and SharePoint. The friction points are price — Microsoft 365 Personal is around $70/year and prices are increasing mid-2026 — and the fact that Copilot processes your email through Microsoft's cloud infrastructure. Inboxed is a meaningful alternative only for individual Mac users who don't need the Microsoft 365 ecosystem and prefer local AI processing.
Frequently Asked Questions
What does Microsoft 365 actually cost in 2026, and is Outlook available without a subscription?
Microsoft 365 Personal costs approximately $70/year ($6.99/month), and commercial plans are increasing in price effective July 1, 2026 — Business Basic rising from $6 to $7 per user monthly, Business Standard from $12.50 to $14.50. A standalone, perpetual-license Office purchase is still available but Microsoft pushes heavily toward subscriptions. Outlook on macOS is not available as a standalone purchase separate from Microsoft 365. For users who only need email and don't use Word, Excel, or Teams, paying for the full Microsoft 365 suite to access Outlook is a poor value proposition — which is one reason alternatives like Inboxed exist.
How does Outlook Copilot's AI privacy compare to Inboxed's local AI?
Outlook Copilot AI runs on Microsoft's Azure infrastructure. When you use Copilot to summarize threads, draft replies, or manage your inbox, your email content is sent to Microsoft's servers for processing. Microsoft maintains strong enterprise-grade security certifications and states that customer data in Microsoft 365 is not used to train Copilot's underlying models. This is server-side AI with contractual data protections — a different architecture than Inboxed's approach of running models entirely on-device via Apple MLX. For individual users outside enterprise agreements, the relevant question is whether Microsoft's privacy commitments are sufficient versus eliminating server-side processing entirely.
Who genuinely needs Outlook and shouldn't consider switching to Inboxed?
Anyone working inside a Microsoft 365 organization should stay with Outlook. The calendar integration with Exchange Server, shared mailboxes, resource booking, Teams meeting scheduling, and admin-managed compliance features are deeply embedded in Outlook's architecture and have no equivalent in independent email clients. If your IT department manages your email through Exchange or Microsoft 365, switching to Inboxed would likely break corporate calendar invites, delegated access, and compliance archiving. Inboxed is designed for individuals with personal or standard IMAP accounts — it is not a Microsoft 365 enterprise email client and makes no attempt to be.
