I wish to open an Outlook window from a hyperlink in a web page. I want the folder list to appear and to show an expanded list of subfolders below the folder I have chosen to open.

I can manage part of it, as I can create a link to open a new window containing the contents of the correct folder, by using the URL Outlook:<folder> and Target Frame _blank:

<a href="Outlook:<folder>" target="_blank">

How can I specify the other two parts
a. display the folder list
b. show the expanded list of subfolers?

(Obviously after the new window has popped up I could go to the View menu and select 'Folder List', and click on the plus sign to expand the list. However, I wish to do this automatically, firstly to save time, and secondly for users who may not realise that they can do this.)
