In a previous post it was asked:
I have added an Organization browser to a page. What I am wondering, is how I can have the browser begin with a specifc user and not the viewing user?
With the answer given:
add the 'accountname' parameter to your URL:
http://www.example.com/orgbrowser.aspx?accountname=domain/useraccount
I did that but it didn't work. It still provides the signed in user's view.
