Geary ou Thunderbird : une bonne alternative sous Linux ?

Geary, alternative Linux à Thunderbird

Mis à jour le 22 octobre 2026

Notre avis

Geary is a solid, lightweight replacement for users who primarily need clean email management on GNOME. It handles IMAP/POP3, multiple accounts, and conversation views well. However, it is not a full drop-in replacement for heavy Thunderbird users. If you rely on Thunderbird’s built-in calendar, contact manager, RSS reader, or chat features, Geary will leave you short. It is best for those who prefer a simple, native-feeling mail client and are willing to use separate apps for calendar and contacts.

Ce qui change

Ouvrir vos fichiers Thunderbird

Geary does not directly import Thunderbird’s mbox or maildir file structures. You cannot simply point Geary at your existing Thunderbird profile folder. However, since both use standard IMAP/POP3 protocols, your email history remains on the server. If you use local storage (POP3), you would need to manually export messages or re-download them, as there is no native 'import from Thunderbird' feature in Geary.

Passer de Thunderbird à Geary, étape par étape

Back up your Thunderbird profile to ensure no local data is lost.
Install Geary via your distribution’s package manager or Flathub.
Launch Geary and add your email accounts using the quick setup wizard.
Verify that IMAP sync is working by checking recent folders.
Install separate GNOME applications for Calendar (GNOME Calendar) and Contacts (GNOME Contacts) to replace Thunderbird’s modules.
Configure desktop notifications in Geary settings to match your previous workflow.

Questions fréquentes

Can I use Geary with Gmail or Outlook.com?

Yes, Geary supports standard IMAP servers, including Gmail, Yahoo, and Outlook.com. You may need to enable less secure app passwords or OAuth2 if your provider requires it, though Geary’s OAuth2 support can be less integrated than Thunderbird’s.

Does Geary have a built-in calendar?

No. Geary is strictly an email client. For calendar functionality on GNOME, you should use GNOME Calendar, which can sync with your email account’s CalDAV server if available.

Is Geary suitable for users who need chat or RSS?

No. Geary does not include chat or RSS readers. If these are core parts of your daily workflow, sticking with Thunderbird or using a combination of Geary and separate apps (like Fractal for Matrix or gPodder for RSS) is necessary.
