Maybe someone can help me. Currently there is a distribution group in Active Directory that contains a number of users and a Public folder. If email is sent internally to the distribution group the public folder gets a copy. If external mail is recieved everyone gets it except for the public folder, and a bounce back message saying the email was not delivered is sent back to the sender.

Check the Client Permissions of the Public Folder. In order to receive external email, a public folder must have Anonymous assigned with Contributor rights, which is NOT the default.

Ensure that the Anonymous permission on the Public Folder is set to a minimum of Contributor.

Giving the Anonymous permission contributor rights, worked for me. I created a email enabled public folder that also could not receive email from the outside. I made the referenced change, and the folder is now able to receive email.

Thanks for the advise.

you may want to check that the Anonymous user is set to at least contributer... with out this unauthenticated users will not be able to send to this address.
