External email to public folder fails
Hello I have a Win2008 ent server with E2007sp1 ent I have mail enabled public folders that can get email from internal senders but if sent from internet users it never arrives Delivery is delayed to these recipients or distribution lists: it@xxxxxreg.net Subject: PF test mail This message has not yet been delivered. Microsoft Exchange will continue to try delivering the message on your behalf. Delivery of this message will be attempted until 9/11/2008 3:58:03 PM (GMT-05:00) Eastern Time (US & Canada). Microsoft Exchange will notify you if the message can't be delivered by that time. There is nothing in any queues and when I use meta there is nothing Any ideas??

Well, Give CreateItems access rights to Anonymous user on that public folder that should give permission to outside usersfor delivering mails to it. Add-PublicFolderClientPermission -Identity "\ITTECH" -User Anonymous -AccessRights CreateItems

the user already had the rights Add-PublicFolderClientPermission : The user, Anonymous, already has some of thepermissions (CreateItems) specified to be added on the public folder \ITTECH.You cannot add a right that the user already has. The current permission forAnonymous is "CreateItems".At line:1 char:33+ Add-PublicFolderClientPermission <<<< -Identity "\ITTECH" -User Anonymous -AccessRights CreateItems

This is the ndr I get from yahoo when trying to send to 1 of the public folders <testpf@eventreg.net>:Sorry, I wasn't able to establish an SMTP connection. (#4.4.1)I'm not going to try again; this message has been in the queue too long.

Clarify: Internal users are able to send mails to public folder, but not the external Please check this thread, theres same symptom as yours Collect info: 1. Is it a single public folder issue or all public folders? 2. Is there any other mail flow issue in the environment? 3. Based on the thread above, check public folder in the ADSIEditor
