To import Contacts (vCard) data into a Contacts-type Mailbox, open its Folder Management page. The page contains the Import Contacts Data control:
Use the Browse button to select a text file with vCard data, and click the Import vCard 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 vCard data elements were parsed without errors).
To export contact data in the old (2.1) or new (3.0) vCard format, click one of the Export vCard Data links.
