We have an Exchange 2010 setup using a number of public folders, one of which is called "Spam". This is a place for employees to post stuff that isn't really relevant to the business but might be among employees (e.g., "I have a room for rent", "anyone know a good dentist?", etc.)
We had a private e-mail message sent to two internal recipients and the e-mail message also ended up in this Spam public folder, even though it wasn't addressed there. Both people say they didn't move it there and upon reviewing their Outlook rules, nothing would copy or move that message to the folder.
Any ideas on what I could check to find out why that message ended up in Spam?
