After finishing this upgrade our Open-Xchange Webmail stopped working with the following errors:

=============

==================.

          Open-Xchange either doesn't allow upgrade of the above mentioned package.  Any Ideas on how to fix this?    Are there any Webmail client alternative to use on the meantime on UCS?

Thanks,

Hello Rolando!

You got a backup of that installation? I think this would save a lot of time. OX is not available for UCS 5.x yet and therefor the update was blocked (“Checking for release updates: The update to UCS 5.0 is blocked because the components ‘open-xchange-text_20210301095207’, ‘oxseforucs_20210520121818’ are marked as required.”).

Cheers

Ben,
The answer might be on my previous post. Look for possible STARTTLS or SSL problems on open-xchange.log.0 .

Hello Vector,

Any news on this? Do you know when it is expected to be ready?

You mean OX for UCS 5? It was recently released. Have a look at the OX App Center page there it says “Available for UCS versions: 5.0, 4.4, 4.3, 4.2, 4.1”
