Thank you for your posting above.
In terms of items 1) and 2), if I understand your comments correctly, you are running into limitations of the GroupWise Address Book application. Unfortunately, we are not able to address these issues as they are inherent in GroupWise.
The contact import process can potentially take some time. This is due to the design of the GroupWise Address Book access API, which can slow down considerably as contacts are added. Again, this is something we are unable to address as third party developers.
Sorry I could not provide a more positive response.
