This is exactly the post I've needed. I have two calendars, one on my personal server running Mailcow (SoGO) and my work calendar with Fastmail. They don't work together- I've never found a way to get mailcow's calendar to work with other tools well, and so I spend time syncing between them semi-manually. I've wanted to de-couple the calendar for a while but the only alternative I knew about was Nextcloud, which I think is a bit heavy weight. This Baïkal looks great and I can't wait to give it a try. Doing this will also allow me to explore changing out Mailcow for another self-hosted mail service.
