Open Xchange does not appears in App Center

Dear Forum

Was Open Xchange been taken off from the App-Center? It does not appear anymore.

Best regards


You’re probably running UCS 4.3. The Open-Xchange app has not been ported to 4.3 yet. It will be made available via the app center once it has been ported.

Kind regards,

Hello @Xela,

Open-Xchange is still available in the App Center, but currently limited to UCS 4.1 and UCS 4.2. The current version of Open-Xchange only run on Debian Jessie and therefore only up to UCS 4.2.

UCS 4.3 is based on Debian Stretch and OX App Suite 7.8.4 does not support it. The next version 7.10 will support Debian Stretch and therefore also UCS 4.3. According to our information, OX App Suite 7.10 will be available in the second quarter 2018.

Best regards,

Hi Nico,

Best regards

Is it advisable not to update an existing system (4.2) with Open Xchange to 4.3 until it is also available in 4.3?

Yes - there are security updates coming for 4.2 for the next few months.
