When adding a caldav calendar shared with me, I keep getting an error message : login failed with a 401 error, though I’m sure my login and passwords are ok (it works in Thunderbird).
At work, we use the format http://url/dav/email.address/calendar
we can have several calendars, and shared calendars.
In thunderbird, you had to add each calendar.
Here, you only have to enter the url up to your email address ( http://url/dav/email.address) and it fetched all the calendars inside my account.
