The Add Contact option is available if the Exchange Integration has been set to synchronize contacts.
To add a contact from Outlook/Exchange to CRM:
If the CRM match rules detected that the contact was already in the CRM database, then it is just added to the My CRM | Contacts list. Note: The contact does not show as linked (CRM Contact category in Outlook) until the next synchronization. At that point, deduplication takes places using Exchange Synchronization deduplication. Please see Contacts: CRM to Exchange for more information.
Go to Exchange Integration home page...
