Windows Messenger V5 and OE

[snoma01]

Windows Messenger V5.0

I use Windows XP Home Edition SP1 and just today upgraded from Windows
Messennger V4.7 to V 5.0 (5.00.482).

I use Outlook Express V6.0 (6.00.2800.1123).

When I was using Windows Messenger 4.7, I was able to see the Messenger's
list on the left hand pane of Outlook Express (together with my contact
lists), but with V5.0 of Windows Messenger, the people on my Messenger list
do not appear any longer.

1) Can some guide me how I can get my Messenger list appear as before?

2) If above is no longer possible with V5, how do I uninstall V5 and
re-install V4.7?

Thank you.
