Error "Failed to connect calendar. Service Unavailable"
How to reproduce:
- Go to Evolution > Calendar view (Ctrl + 3)
- Go to File > New > Calendar
- Choose 'On the Web'
- Enter Name, URL etc. > Klick OK.
Evolution keeps showing me following message:
Failed to connect calendar [calendar-name]. Service Unavailable
Despite the error message, Evolution (and Gnome Calendar) are showing the events from the calendar.
It happens only on calendars which are shared by an url starting with
https://outlook.office365.com/owa/calendar/...
The calendar is read-only and is available.
Edit: Sidenote: Evolution is asking me for username and password, even though these calendars do not need these to be able to read them.
I would like to give more details for debugging but would need further assistance on how to do that.
Evolution 3.28.5
Gnome 3.28.2
Manjaro 17.1.12
