External email not being delivered to Public Folders
Posted on 2006-07-21
We are running Exchange 2003 Enterprise with the latest patches. I have a Public Folder that has an SMTP address on it. Internally I can send email to that folder, but if an email comes to it from the outside, i.e. my personal email account, the Exchange Server refuses it with no type of error message, other than "delivery to the following recipient failed".
Is there some setting in Exchange 2003 that disallows delivery to Public Folders from external email addresses for security reasons or something? How can I change this?
Any help would be appreciated. Thanks.
