We have deployed a new Exchange server in our domain and successfully moved all data, mailboxes and traffic to that server. The Public Folder tree was also created on the server and all PF's were replicated and then moved tothat tree. All of this worked fine until I tried to remove the Public Folder store from the original server, at that point all externalemails with a public folder as it's destination began to bounce. I can't figure this out, any help would be greatly appreciated. Thanks Mark

This can be fixed quite easily. Use the powershell command to remove the folder as a mailenabled folder and then recreate it. Disable-MailPublicFolder -Identity Foo Enable-MailPublicFolder -Identity Foo Worked for me
