In a Microsoft Exchange Server 2007 environment, you create a hidden message in your Inbox folder. If you log on to the mailbox by using an IMAP4 client, the hidden message is downloaded and visible.
Note This issue does not occur in other clients, such as Microsoft Office Outlook Web Access (OWA), POP3 clients, or MAPI clients.
