Error: Failed to load messages on OXSuite App

Hello,
I just created a server following this guide:
https://oxpedia.org/wiki/index.php?title=AppSuite:Open-Xchange_Installation_Guide_for_CentOS_7

But for some reason, the server does not load my emails. How can I fix this?

Here is the error that I see on the server:

An error occurred inside the server which prevented it from fulfilling the request. (ID: -803819017-12 / MSG-0008) 1/4/2021 5:39 PM

Thanks.

There is a dedicated app called OX App Suite in the UCS appcenter (https://www.univention.com/products/univention-app-center/app-catalog/oxseforucs/).
Please use that one to get a working OX installation.

Greetings
Daniel Tröder

Hello,
I did that.
Installed a UCS server and from there I installed OXApp. I do have a question now, how can I add the rest of the features of the OXApp like the Document edition and sharing?

Thanks.
