Hello @all,
i’m new here and this is my first post - so, if something is not ok, please let me know!
At the moment we are evaluation the possibilities with eMClient under windows and recognized, that most of the well-known things in Outlook are still working 
One thing we have no solution found for is the problem with our calendars: we are 5 users and have an exchange 2019 box here (on premise, latest patchlevel).
In Outlook every user has given the full rights (publishing editor) to the college, so in Outlook everybody can do everything in the others calendar - fine for us.
In eMClient this is not possible, we all get the calendar of the others, but we are unable to change anything in it?!
e.g. the message we get is:
in diesem Kalender kann kein neuer Termin erstellt werden. Der Ordner ist schreibgeschützt - this is german and means something like: access denied, write protected folder
Can someone help me with that?
Thanks in advance - and happy easter to all of you
Joachim
