Did you know you can set up custom search folders to contain only the emails that you want?

Create a Search Folder using one of below three methods:
  1. Through the Menu > File > New > Search Folder…
    2. By clicking the     New button dropdown menu in the standard toolbar > then Search Folder
    3. Right-click the     Search Folders folder in left pane > then New Search Folders…

    Which brings us to below screen:


I set up one for Mail flagged for follow up, but you can set up as many as you want.

On my version of Outlook (Office 2010), this search folder appears like this: Right click on the folder and select Show in favourites. This will display the folder at the top of the left hand column in Outlook. The folder is not moved, it just has a link in favourites.
