Here’s a little issue that can stump quite a few people because the solution isn’t real obvious.

Scenario: You setup a mail enabled public folder in Exchange and it works great internally. You send some test messages from a public web mail account and nothing shows up. You check your inbound mail filter (you do have one, right?) and it shows a delivered status. No error messages, no Non-Deliverables, it just disappears into a black hole.

 The answer?

Add “Anonymous” as a contributor to the public folder permissions.

Simple solution, yet it took me quite a bit to find the answer. I hope I”ve helped someone else that may be pulling their hair out.

Exchange 2000
Exchange 2003

Note: I have not tested on Exchange 2007
