Hello Community, I was wondering what do you guys use for team/shared calendar? As I want a self-hosted solution (not gmail or office365) at the moment I'm running a local calendar within my Thunderbird installation but I have a feeling there must be a better way to allow collaboration. What do you guys use that is easy to setup with the typical perfect server ISPConfig3/Ubuntu 20.04 installation? Owncloud is obvious solution but it seems too bloated for a simple shared calendar. Thanks for your thoughts. My apologies if this is not the right place to ask such a question - mods please feel free to move it.
