Format
The iCalendar (ICS) format is used to import and export calendar events. Files in this format are regular text files with the .ics extension, which contain separate vEvent records with information about each event — name, start and end date and time, description, etc. The format is suitable for transferring events between calendars in WebMail.Online, Google, Proton, and other services and mail clients.
Import
Only events created for the same mailbox via the WebMail classic interface can be imported from WebMail classic.
