Introduction
You can check your emails using other email programs (like Mailbird, Microsoft Outlook or Mozilla Thunderbird). Using desktop email programs will make you more productive and your email will always be available, even offline. Setup Your Posteo.org Account with Your Email Program Using IMAP.

This page compares the features of Mozilla Thunderbird 60 (download) and Microsoft Outlook 2019. LibreOffice does not have a PIM module and therefore users looking for a suitable PIM software need to seek alternatives for email, calendars, contacts, tasks, and chat features. This comparison table has the objective to assist users in this search. Mozilla Thunderbird is a fully-featured PIM tool. Like LibreOffice, Thunderbird is a free, open-source, cross-platform program. There are alternatives to Mozilla Thunderbird available, such as Evolution and Kontact.
Please note that neither the LibreOffice developer team nor the Document Foundation gives any official recommendation for a PIM software replacement for LibreOffice.
This table separates major and minor feature differences and also includes notes on Thunderbird add-ons. The comparison highlights differences and therefore does not display any features which are present in both PIM programs.
The feature comparison table is work in progress and currently incomplete. |
