Hi,
As per the information and details provided by you, I think you want default search folder in outlook 2010.
In Outlook 2003, 2007 and 2010 these three are the Default Search Folders: -
The Categorized Mail Folder
The For Follow Up Folder
The Large Mail Folder
You can also add many Search Folder as you want.
Click on Search Folder and then choose New Search Folder.
In the New Search Folder dialog box, you can choose from a variety of present folders or you can also create your own folder.
Correct me if the information that I am having is wrong.
Thanks and regards
