We are using Exchange 2003 SP2 with a front-end and a back-end server. I have mail-enabled a public folder located on the back-end server and set up anonymous with contributor access on this folder. I am not replicating folders from the back-end to the front-end, but I do have the public folder store mounted on the front-end.
Messages from external accounts are hanging in the front-end queue, but messages from internal accounts are delivered correctly. I'm assuming that an NDR will be generated eventually, but we just started trying this and the messages haven't expired yet.
I've seen posts talking about unmounting and deleting the public folder store on the front-end server, but we are runnning OWA and it has an OWA scratch pad public folder on the front-end server. If I unmount and/or delete the PF store on the front-end server, what effect will it have on OWA?
