I have a public folder with an external SMTP address which is no longer getting messages from the internet. The NDR states that another folder in the system has the same SMTP address. I cannot find it, nor do I know of a way to search public folders for a duplicate SMTP address. Event logs have no info. I tried a directory export, but it doesn't include public folders. Does anyone know how I can find this troublesome folder? This is a mixed E2K E5.5 environment.
