Native mail and calendar client for Windows.
I'm a big fan of Windows Mail & Calendars due to its simplicity. Personally, I find it more intuitive for daily use cases compared to Outlook desktop and the new WebView2 powered Outlook version. Seeing Microsoft deprecating it dragged me into starting to work on Wino a couple of years ago. Wino's main motivation is to bring all the existing functionality from Mail & Calendars over time without changing the user experience that millions have loved since the Windows 8 days in Mail & Calendars.
Wino vNext focuses on making Mail, Calendar, and Contacts feel like one cohesive native Windows experience while improving sync reliability and startup responsiveness.
- 📅 Calendar management: Event compose/create flow, calendar-mail mapping, reminder snooze support, occurrence and detail-page improvements, and CalDAV correctness fixes.
- 👥 Contact management: Improved contact workflows, account/settings integration, and contact data-model cleanup.
- 🔄 Synchronization reliability: Refactored synchronizers, better state handling, 404 + 429 error handling, and duplicate-operation prevention.
- ✉️ Compose and drafts: Refined editor/toolbar architecture, better rendering pipeline, Gmail draft support, and large Outlook attachment upload sessions.
- ⚡ Performance and quality: Faster mail fetching with batched DB queries and caching, SQLite indexing/foreign key enforcement, and broader test + CI coverage.
