We have a single Active Directory domain, single Exchange site, and single mail server (Exchange 2003 Standard Edition, Service Pack 2, 32bit) running on Windows 2003 Standard server, Service Pack 1, 32bit). Our users are running Outlook 2003 Professional on Windows XP SP2 PCs.
The problem is that in a particular mail-enabled public folder, the messages that arrive in there show up with a Post icon instead of an Envelope icon. So, if you open those messages you don't get the normal email options, just the Post options, so you have to use the Action menu to reply to it. How can I make sure that any email that arrives in this public folder keeps the Envelope icon?
