Contacts can be imported into the Webmail address books from vCard and CSV files.
Click the Import button from the top toolbar in the address book view to open the import wizard.
Then select the file to import from your computer’s hard drive. Make sure it’s either .vcf or .csv file.
Select which address book the contacts should be imported to. The checkbox let’s you delete all contacts from the selected address book before importing. Be careful with this, the deletion cannot be undone!
Click the Import button to start the importing process.
The next screen will display the results of the import process. Click Done to get back to the address book view and see the imported contacts.
