It is possible synchronise the Calender between email on Desktop-Computer
and Smartphone-App ?
works fine with caldav.
if you use a mail service that supports caldav
on pc you connect to it via mainmenu/accounts there is a tab for caldav.
on ios you must go to settings and mail then accounts. (don’t know about android.)
synchronisation may take a while according to synchronisation setting on each device
etiquettes may not work across operating systems but the flags do.
connections on Linux (Evolution,Thunderbird_calendar, Kontact_Calendar) also work

eM Client upcoming droid and ios app will sync Calendars when released hopefully not far away.
In the meantime I sync eM Client desktop calendars to my local Gmail & Outlook mail apps till the eM Client mobile app is released later.
