share editable icould calendar

how can I share Icloud calendar and make it editable on EmClient?

If you already have an iCloud calendar, simply add that to eM Client by going to Menu > Tools > Accounts.

Once the calendar is setup in eM Client, any changes you make will be synced with the server.

Depending on your calendar provider, you might be able to share that calendar or not. You will need to check with them if that is possible.
