Overview of server-side settings mainly hiding/disabling front end elements without affecting backend. Please mind that this listing isn't complete yet.
Folders: hiding folders in panel
In order to configure this server-side, just create a new property file in /opt/open-xchange/etc/settings or append to the existing file /opt/open-xchange/etc/settings/appsuite.properties (mind the double-slash; this in not a typo!):
io.ox/core//folder/blacklist/<id> = true|false
example: hide global address book
io.ox/core//folder/blacklist/6 = true
Please take a look at the media player article
