Hello,

I have a problem problem.
I configured an user which calendar is shared for a group/allocator. The user which was in this group at the point of time of sharing get an email and can visit the calendar.
But user which I added later to the group and which want to get access to the calendar with NEW CALENDAR -> Sync Dates with external Calendars and the url for example http://zimbra.example.com/home/<user>/Calendar can't connect.
There is an Error in maillog.log

Code:
com.zimbra.common.service.ServiceException: resource unreachable: HTTP/1.1 401 permission denied you do not have sufficient permissions

How can I solve this problem.
Is there another way to realise an public calendar for all users??

Thanks
