Download Zimbra 9 FOSS

Latest Version 9.0.0 (patch 25)


only for Ubuntu 18.04 LTS

Update! Now Zimbra 9 FOSS version is again available for download!

Due to the changes in the Zimbra github source repository, the standard Zimbra 9 build process results in the compilation of Zimbra 9.x which is the development version (probably 9.1) of Zimbra Collaboration Suite. This development version is not compatible with other Zimbra core components and Zimbra patches. We have managed to compile Zimbra 9 from sources as close as possible to the Zimbra 9 Network Editon.
Unfortunatelly, for those who downloaded our Zimbra 9 FOSS version before 1.1.2022, there is no easy path to downgrade to the our newest version. The easiest way is to uninstall the old Zimbra version and install the newest one.
