can't share calender

I have the free version of eMClient installed on my system.  I am unable to share my calendar through exchange.  Whenever I choose someone to add in the who can access my account settings, they seem to be added, but “disappear” when I leave that screen.  I can see their calendar, just can’t share mine with them.  Any suggestions?

Hi, unfortunately shared calendars on Exchange are not supported, only delegated calendars at the moment.

Thank you for understanding, I hope you can manage to use the current settings,
