MS Outlook Plugin for IM

Hello,

I wanted to know is it possible to integrated Spark with MS Outlook for sending or adding contacts directly from Outlook (Like Office Communicator -- screenshot attached).

Also I want to know how I can add contact groups like ... If there is a group named "XYZ" available in AD and there are 3 person added in that group, Rather adding all 3 separate I want to add only group "XYZ" and it should add all 3 person on my contact list.

Thanks in Advance
