Mozilla Thunderbird als Linux-Alternative zu Microsoft Outlook
Aktualisiert am
Unser Fazit
Thunderbird can replace Outlook for most Linux users who need standard email, calendar and contact handling. It covers IMAP/POP, basic scheduling, and contacts, and with the Lightning add‑on it offers a functional calendar. Power users who rely heavily on Exchange features, advanced meeting management, or deep PST integration will find gaps, but for personal or small‑business use Thunderbird is a solid, free alternative.

Ihre Microsoft Outlook-Dateien öffnen
Thunderbird cannot open Outlook PST files directly. Users must first convert PST to MBOX or EML using external tools, then import those into Thunderbird. Exporting from Thunderbird to PST is also not built‑in; an intermediate format like MBOX is required before using a conversion utility.
Von Microsoft Outlook zu Mozilla Thunderbird wechseln – Schritt für Schritt
- Export Outlook data to PST (or use Outlook's export to CSV for contacts).
- Convert PST to MBOX/EML with a trusted conversion tool.
- In Thunderbird, use File → ImportExportTools NG to import the MBOX/EML files.
- Install the Lightning add‑on for calendar support and configure your calendars (iCal, Google, etc.).
- Set up your email accounts in Thunderbird using IMAP/POP settings.
- Verify contacts and calendar entries, then decommission Outlook.

Häufige Fragen
Can Thunderbird sync with an Exchange server?
Only via third‑party extensions like ExQuilla or Owl; native MAPI is not supported.
Does Thunderbird support meeting invites and responses?
It can receive iCalendar invites and send responses, but lacks some of Outlook's meeting‑room and delegate features.
Is there a way to import Outlook tasks into Thunderbird?
Tasks are not directly compatible; you would need to export them to a generic format (CSV) and import them into a Thunderbird task add‑on, if available.
