To import Calendaring data into a Calendar-type Mailbox, open its Folder Management page. The page contains the Import Calendar Data control:
Use the Browse button to select a text file with vCalendar or iCalendar data, and click the Import Calendar Data button.
If there is an error in text file format, the error message is displayed indicating the text line that caused the problem, and no data is imported (even if some calendar data elements were parsed without errors).
All iCalendar import file items that have the CANCEL method are used to remove existing items from the Calendar-type Mailbox. All other items are "published" in that Mailbox, i.e. they are stored in the Mailbox and all other items with the same UID are removed from the Mailbox.
To export calendaring data in the iCalendar format, click the Export Calendar Data link.
