Wino Mail

Motivation

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 started before the current AI era. The project welcomes AI-assisted contributions when they comply with its coding rules, architecture, and maintainer decisions.
