It’s not just office, SH has been slowly replacing the entire O365 suite with OpenDesk, which is an open source product based on Matrix, Jitsi, LibreOffice, and a few other tools.

The goal is to have a fully integrated solution for calender, chat, calls, documents, cloud storage, etc.

My employer is developing parts of that solution and we recently switched our internal communication over to it, and tbh, it’s working really well.

Now is the perfect point in time to do it, with the GDPR ruling regarding O365 and Microsoft fumbling the migration between old teams and new teams.
