Im setting up an Outlook 2011 to fetch mail from an IMAP server.

The I've subscribed to all the folders on the imap server, and I can delete and create folders from Outlook and it is reflected on the server. But When I wasnt to delete a single email from the inbox, the Changes I do are not reflekted on the  server.  under the delete otions I have chosen that the fiels should be copied to the "delete items" folder on the imap. and when I delete folders this is where they go.

Why cant I change single emails?  help!
