To import Tasks data into a Tasks-type Mailbox, open its Folder Management page. The page contains the Import Tasks Data control:
Use the Browse button to select a text file with vCalendar or iCalendar data, and click the Import Tasks 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 iCalendar data elements were parsed without errors).
To export Tasks data in the iCalendar format, click the Export Tasks Data link.
