Thunderbird
Free desktop email that still respects your inbox.
Thunderbird is Mozilla's free mail client: fast, extensible, and still actively shipped. A favorite exit from Outlook for personal accounts.
It is weaker as an Exchange-room corporate calendar. For IMAP and personal mail, it is the classic free pick.
Why it's here
- Free and actively maintained
- Solid IMAP/JMAP personal mail
- Extensions and a real desktop UI
- Light on deep Exchange workplace features
