Received an inviation for an outlook user.
klick accept
A message appears that no prior version of this invitation could be found. This is quite likely, as it is the first invitation from this user.
After I click 'OK' a mostly empty pop-up appears (see attachment). My guess is that it is looking for a calendar. As nothing is displayed, I press 'cancel' (Abbrechen)
Result: A confirmation email is sent to the invitor, and the invitation is removed, without being in any calendar. Thats no good....
Expected result: If the action is cancelled, it should be cancelled....and not processed with a destructive result.
 Standard calendar should be used (as created during setup)
