In OCS 2007 there was a tool you could use to automatically push out contacts to your OCS users. This was helpful so the end user would not have to go enter everyone they wanted to their contacts manually in the Communicator client.
This tool was called LCSAddContacts and it was a script you ran on the server. Well in Lync 2010 Microsoft did not add this ability into Lync 2010 and the LCSAddContacts no longer exists. Fortunately MVP Jeff Guillet has created a tool called LyncAddContacts that can do this for Lync 2010. Here is the link to that tool:
