Prerequisities

Lync Client SDK must be installed first. It can only be installed on 64 bit Office. If you have a 32 bit office you have to uninstall it and run fixit (a microsoft tool and can be downloaded and installed free from MS web site). Office 64 bit then can be installed after a restart.

Sample code

To search for people in the UCS address book

1. Get the string used as the name search criteria.
2. Call the ContactManager.BeginSearch method.
3. In a lambda expression or a callback method passed in the second argument of BeginSearch, get the results of the search by calling the ContactManager.EndSearch method.
4. A Microsoft.Lync.Model.SearchResults object is returned.
5. Get the number of people in the search results by reading the SearchResults.ContactsCount property. If the number is zero, nobody in the address book matched the search criteria.
