IMF Confusion – Store threshold rating text in UI

A major source of confusion regarding the Store threshold value used by Intelligent Message Filter (IMF) is the IMF UI itself. This is documented in Intelligent Message Filter release notes.

You create new Query-Based Distribution Groups but they don’t show up in the All Groups address list in Outlook clients – cached mode or not. QBDGs are not really groups, as far as Active Directory goes. They’re instantiated from a new class – msExchDynamicDistributionList. The default ldap filter for All Groups address list, stored in […]
