I have a user who is trying to configure the Unread Mail search folder for a shared mailbox in Outlook 2007. I believe last time we accomplished this by doing an advanced find, and saving the search. However, on this computer I can't search more than one folder of the shared mailbox at a time.
Everything I have read online says this isn't possible, but we have one user who has it set up and working perfectly. There's no additional software or indexing, not even Windows Desktop Search 4.0 updates installed.
