Thunderbird als Linux-Alternative zu Windows Calendar

Unser Fazit
Thunderbird is a solid replacement for Windows Calendar if you also use email and want a unified inbox with calendar integration. It supports Google, Microsoft Exchange/Outlook.com, and iCloud calendars through add-ons or manual CalDAV setup. The monthly view, event creation, and reminders work well. However, it’s heavier than Windows Calendar and requires some setup for calendar syncing. It’s best for users who want email and calendar in one app and don’t mind a steeper learning curve.

Ihre Windows Calendar-Dateien öffnen
Thunderbird supports the standard iCalendar (.ics) format, which Windows Calendar also uses, so you can export events from Windows Calendar as .ics files and import them into Thunderbird. This works reliably for single events and calendars. However, recurring events or rich formatting may not always transfer perfectly. There is no direct import tool for Windows Calendar’s native files, but since both use open standards, manual .ics transfer is effective for most users.

Can Thunderbird sync with Google Calendar?
Yes, Thunderbird can sync with Google Calendar using the built-in provider or CalDAV. You may need to enable CalDAV in Google Settings or use an add-on like Provider for Google Calendar.
Does Thunderbird support iCloud Calendar?
Yes, but not directly. You must manually add iCloud’s CalDAV server in Thunderbird’s calendar settings using your iCloud credentials and server URL.
Is Thunderbird lightweight like Windows Calendar?
No, Thunderbird is more resource-heavy because it combines email, calendar, contacts, and feeds. If you only need a calendar, consider a lighter tool like GNOME Calendar.
