OpenMailClient
Clone of Outlook
Free clean-room email program that works like classic Outlook: ribbon, folder pane, message list and reading pane, and it opens your .pst files.

What works the same as Outlook
- Outlook's classic window: ribbon, folder pane, message list grouped by date and reading pane.
- Opens .pst and .ost data files, and the .pst files it saves open in Outlook. Saves messages as .msg, .oft or .eml.
- Calendar with day, work week, week and month views.
- Tasks and the To-Do List, with flagged mail beside your tasks.
- Brings in your accounts and data files from Outlook without changing them.
What is missing
- No Mac version yet.
- No sign-in with Microsoft or Google accounts yet: mail accounts use a password.
How to get started
- Click Download and pick the installer for Windows or the package for Linux.
- Windows may ask whether to run the installer, because it is not signed yet. Choose More info, then Run anyway.
- Open it and add your mail accounts, or bring them in from Outlook.
