If you want to see the comparison of LibreOffice suite vs. MS Office, see here: Feature Comparison: LibreOffice - Microsoft Office.
Introduction
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.
