calendar import create double entries


I have to import regulary an ics-file (created from an xls-sheet) into a calendar. Unfortunatly each import creates another simalar entry, if this already/still exists in the calendar.

How can I configure, that an already existing entry in the calendar will overwritten or not imported or a selectbox maybe give me a choos?


There is no such option available in eM Client. If you don’t need to keep existing data, you can create a separate calendar in eM Client as the destination for the import, then just delete that calendar and create a new one before the next import. 

Alternatively you can import the new data into a separate folder/calendar, then use the Deduplicator (Menu > Tools > Deduplicator) to remove any duplicates from the new calendar. Finally move any remaining events to the first calendar.
