ONLYOFFICE Desktop Editors als Linux-Alternative zu Microsoft Office 365
Aktualisiert am
Unser Fazit
ONLYOFFICE Desktop Editors is a solid, free replacement for the core productivity components of Microsoft 365, specifically Word, Excel, and PowerPoint. It handles standard document creation and editing well, with strong .docx, .xlsx, and .pptx compatibility. However, it is not a complete 1:1 swap for the full 365 suite because it lacks a built-in email client and native calendar/contacts management. If you need Outlook functionality, you must pair this with a separate client like Thunderbird. For users who primarily work with documents and spreadsheets and can use third-party tools for email, this is a capable, open-source alternative that runs natively on Linux.

Does ONLYOFFICE replace Outlook?
No, ONLYOFFICE Desktop Editors does not include an email client. You will need to use a separate application like Thunderbird or Evolution for email, calendar, and contacts.
Is ONLYOFFICE completely free?
Yes, the desktop editors are free and open-source under the AGPL-3.0 license. There are no subscription fees for the core productivity tools, though cloud services you connect to may have their own costs.
Can I collaborate with people using Microsoft 365?
