I synced about 13,000 CRM contacts to a new Outlook Address book and Outlook is now unacceptably slow.  A few questions.

1.   What's the easiest way to delete that address book so that I don't delete the contacts in CRM?

2.  Is there a way categorize contacts in CRM for synchronization into Outlook?   For this first attempt I synced everything, then was planning on removing the "Zoho" category in Outlook for selected contacts.
