Tell Outlook which IM client to use for presence

Here are some notes I have to tell Outlook which IM client to use for presence. This stuff doesn't break much, but if you have exhausted all other options, check these out.

Set Outlook to only use Communicator

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\PersonaMenu\RTCApplication
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\PersonaMenu\RTCApplication

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

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\IM\SetOnlineStatusLevel
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\IM\SetOnlineStatusLevel

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

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\PersonaMenu\QueryServiceStatus
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\PersonaMenu\QueryServiceStatus

REG_DWORD
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

Office 2003 SP3 has a fix to get presence when sip uri is in a different domain than default profile user domain. Office 2003 needs to have two reg keys set to get non-buddy presence and dynamic presence. Both can be applied using Office 2003 group policy as well. This is automatically set in Office 2007. If you have Office 2007, pls see below.

Please make sure that this registry key is set:
[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\PersonaMenu]
"QueryServiceForStatus"=dword:00000002
"EnableDynamicPresence"=dword:00000001


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

[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\PersonaMenu]
"Enabled"=dword:00000000
