What works the same as Outlook

  • Outlook's layout: side rail, folder pane, ribbon, message list and reading pane.
  • Flags, colour categories, rules, conversations and search.
  • Calendar with day, work-week, week and month views, meetings and recurring events.
  • Signs in to Outlook.com and Microsoft 365 on Microsoft's own page.
  • Also runs in a browser tab.

What is missing

  • It's a public beta: much of what a daily mail program needs is still to come.
  • Other interoperability limits are listed in docs/gaps.md.
  • The browser version only reads mail from a few kinds of servers; you bring other mail in from files.

How to get started

  1. Click Download. It opens the project's releases page.
  2. On Windows, run the .msi installer; on a Mac, open the disk image; on Linux, pick the AppImage, .deb, .rpm or Flatpak.
  3. The builds aren't signed yet, so Windows and macOS ask before running them.
  4. Try it first with the sample mailbox, or add your own account.
