Using the lastest version of smarter mail and outlook 2013.
I have full control of other users calendar, and have no problem with access on the web interface to this users calendar.
But in Outlook 2013 i can add the shared calendar of this user, but it comes with an error : Could not be updated
we are using imap and not EAS....
This is a problem and a very much requested feature from our customers ! Do we really need EAS for this to work ?
