Stop MSN Connector from synchronizing

Anyone know how to get Outlook 2003 (with the Outlook Connector for MSN) to
stop synchronizing every few minutes? I've turned off all the
synchronization settings I know of in Outlook 2003, but it still
synchronizes MSN accounts every few minutes. Fortunately, it doesn't
synchronize my other email accounts. (I've already tried creating a new
send/receive group and putting the MSN accounts in that group, disabling the
main group, but that doesn't work.)

Thanks.
