How can I connect an iCalendar to Exchange?
Since version 1.36 it is now also possible to import calendars in iCal format cyclically. The iCalendar format is often found on the Internet when it comes to sharing calendar data with others. Examples include Google Calendar, Office 365, Shared Calendars, Holiday Calendar, Garbage Collection Calendar, Event Calendar, and more.
You can use a calendar in ics format in ExMixedFolders by creating a new "CSV / iCal / Excel" job and specifying the iCalendar as the file name here. It can be a local file or an url.
