Root level? Is it visible in the UI? If so it would probably be accessed as:
myFolder = oNameSpace.Folders.Item("Backup");
Formatted how?
If you get a handle to an email you can call its Reply function and get back
a reply mail item.
See www.outlookcode.com for lots of Outlook programming examples, including
C#.

Thanks Ken,
I have been trying to use the reply method of the mailitem but doesn't
appear to work (or maybe I do not undertsand how it works).
In the application that I am writing I loop through all items in my
inbox and for certain emails I parse the message body and accordingly
take some actions such as move the email to another folder and
sometimes send a reply message to the originator. What I meant by
'formatted reply' was add the RE prefix to the subject of original
message, have the oroginal message in the reply's body with the email
header information and a line separator just as you get when you
manually reply to an email.
Cheers,

If you use the Reply function the RE:, etc. are added automatically.
