I just bought an new iMac and Office: mac2011 and I'm in the trial mode for the software.  No problems so far with Outlook connections to mail server, but Outlook won't let me create a new folder to store emails.  When I go to Help or New, other options are available but Folder remains in shaded grey, ie. not an option to open a new folder.

I've tried putting Outlook into Offline mode, but this doesn't help.
