As per https://gitlab.opencode.de/bmi/opendesk/info/-/blob/main/OVE...

This has:

  * libreoffice online
  * element / matrix
  * jitsi video conferencing
  * nextcloud file/data synchronization
  * dovecot imap server
  * identity management via samba4
  * xwiki - wiki

Seems nice.

The alternative offers open source solutions like Nextcloud and Matrix

which would be better in terms of dependence on an US company that can shutdown operations at any time, if one (!) person in charge says so.

And, as we can see, its obviosly a weapon that hasn't been used right now - in oppposit to (stupid) tariffs calculations.

The germans should foster the development of OpenDesk based on OSS like it is proposed and already done. MSFT should be ditched, Linux and open source should be welcomed.
