Hi, And thanks for a great performer. My question is what will happen if I want to filter spam on two mailboxes that I have access rights to, in Outlook. (2003 11.8002 SP2 XP) If the other mailbox is a shared one, with other users also wishing to benefit from the spam filtering (=we all agree what is spam), who should run Spambayes, and are there authorisation issues?
