Move Folder Fails "Cannot copy this folder because it may contain private items" Outlook 2010

I have Two Email accounts at my exchange 2007, and I useMicrosoft Outlook 2010.

I use one of the two addresses through a full access permition given by the administrator.
The problem is that while trying to move one folder from the secondary (Full Access) email inbox it gives me an error that"Cannot copy this folder because it may contain private items" and refuses the move the folder

How can I resolve this issue?
