I have just deployed a new Windows 7 machine with Microsoft Office 2010 installed. The user is complaining that they are unable to click and drag any email message from their inbox (or otherwise) to any other folder. When they attempt this operation when the mouse over any of the folders the pointer turns into the circle with a line through it and when the mouse button is released the message returns to its original location. Yet the user can right-click on a message and utilize the move command in the context menu no problem. I have also verified that Dragging & Dropping is enabled in the Start Menu properties, as well as testing dragging & dropping on the desktop with no problems.
