Adding Contacts and Tasks Support
If you are using the GroupWiseSync Premium account you will need to activate Contacts
and Tasks on your GroupWiseSync client.
To do this you first need to ensure that you are using the latest release of the
GroupWiseSync client. You can do this by using the Check for updates option
inside your client.
Once you are using the latest release of the client you simply need to perform a
sync with your GroupWiseSync Premium account. When this sync is complete you will
see the Contacts and Tasks options appear on the main page of your client.
Select the Contacts and Tasks check boxes and sync again.
