Troubleshooter: Understanding IMF's Interaction with Public Folders

Does Exchange Intelligent Message Filter (IMF) filter out spam messages that are addressed to mail-enabled public folders?

No. The IMF functionality that moves messages while they're in the Store depends on the existence of a client-created Safe Senders list or mailbox attributes that are created when a Microsoft Office Outlook 2003 or Outlook Web Access (OWA) client modifies the recipient mailbox's Junk E-mail Filter settings. Because mail-enabled public folders lack such attributes, IMF has no way to move messages for those folders. Therefore, IMF will set a spam confidence level (SCL) property for incoming messages that are addressed to public folders, but the Store won't take any action based on that SCL.
