Tell Outlook which IM client to use for presence by computerhighguy

Set Outlook to only use Communicator


0 = Default
1 = MSN
2 = Windows Messenger
3 = Communicator <-- Choose this one


2 = Alloweverywhere
3 = Communicator <-- Choose this one


0 = Receive status information only about people who are in your contact list <-- Outlook 2003 Default
1 = Outlook requests status information from Exchange IM service about people who are not in contact list
2 = Uses RTC Service about contact who may or may not be on your contact list. <-- Outlook 2007 Default

The easiest way to disable all presence integration in Outlook is to set this key:
