I have a new deployment of public folders within an existing Exchange 2010 environment. I've created the first folder, mail enabled it and set an inbound mail address. Now, when I email that address, it appears in that public folder but as a post. I've tried to change the type from post to message, but it will not let me (errors as unable to set content to that type for that folder). I understand that a post and a message are to all practical senses the same, but I would like to know how to modify it to be a IPM.NOTE for normal emails. I think it may be caused by having started with a 2003 server and then migrating to the new 2010 box, but there must be a way of changing it over.
