Active Directory and Mail Enabled Public Folders

Sorry if this isn't directly Windows 7 related...but I'm struggling with it nonetheless.

I'm having an issue setting up a Mail Enabled Public Folder. I have the folder created, and anonymous are given proper access to allow incoming messages. My Exchange version is 2010 SP1, full updated, running on a Windows Server 2008 R2 box. Whenever I send a message to the mailbox's address, I get an undeliverable:

[email protected]
#554 5.2.0 STOREDRV.Deliver.Exception:ObjectNotFoundException; Failed to process message due to a permanent exception with message The Active Directory user wasn't found. ObjectNotFoundException: The Active Directory user wasn't found. ##

I know the e-mail address is typed in correctly, but I can't seem to figure out why messages aren't going through. I searched online and found some suggestions, all of which either didn't pertain to our environment, or involved patches...which I have installed.

I found a solution and after working up the courage...I gave it a shot. It worked!
