Existing calendars and tasks can be imported into Mail Basic and Mail Business using the iCalender data format. This article explains how to do this.

Importing a Calendar with ICS/ICAL File

To import a calendar into IONOS Mail:

Log in to your Mail account.
Select the calendar icon on the menu bar.
Click on the Add new calendar link on the left side below the month overview. A context menu will open.

Optional: Activate the Ignore existing appointments option to re-import appointments that already exist in the calendar. This will result in multiple entries.
