It is possible.    I used to run a MS system that way.     All you have
to do is tell Mailscanner not to use spamassassin, and then run spamd
separately.     There is a HUGE performance hit by running it this way
though.   The same server used to be pegged close to 100 % utilization
until I switched to having MS call SA directly, and it now runs around
10-20% utilization, and that's even while increasing the number of
emails/spam/whatever every day.

I'm not familiar with the Outlook plugins you're talking about, but it
might be worthwhile to look at the end result of what the plugin's do.  
 For example, can a user modify his/her own .spamassassin/user_prefs
while with the plugin?    If so, allow that, and then write a simple
cron type script to convert everyone's user_prefs file into SA rules
files.   This way you can get the best of both worlds.
