I have another question:
The new multi-user Calendar-view is great - but we have one thing, which
is confusing to our users:

User A has a shared calendar (the owner of this shared calendar is User
B). It is clear, that User A can see appointments of this shared
calendar in his "main Calendar" if this shared calendar is "enabled".
But User A cannot see the calendar items of this foreign shared
calendar, if he changes to the new multi-user - view.

Does this work as designed or is it a bug?

Thanks a lot
