Great to get confirmation!
To wrap up your wrap up:
I won't bore you with the details, but the data on the server was absolutely fine and it only affected how the events appeared on the webmail site.
It's always fun to play around with new stuff 🙂
The webmail calendar is actually a CalDav calendar, you can set it up in any CalDav supported calendar application (including on your phone), or you could use the calendar built into Vivaldi Browser 😉 and then it will sync between your devices (and the webmail calendar).
In the top menu in the webmail calendar there is an export button that will give you a ICS file that you can import in most calendar applications, also most CalDav clients have an export function (this includes Vivaldi Browser).
I, of course, would recommend using the
Vivaldi Browser built-in Calendar, otherwise we have a help page on how to
get the URL for other CalDav clients.
Since it was a bug on our side I won't mark it as solved, we use that for issues users can fix themselves.
