Restore the unread mail folder of Outlook

My colleague Outlook's unread email folder is missing. Use this method to restore it:
 
 
 
The Unread Mail folder is one of Outlook's default Search Folders. If deleted, you can create it again.
 
In Mail, on the File menu, point to New, and then click Search Folder.
TIP You can also open the New Search Folder dialog box by pressing CTRL + SHIFT + P.
 
In the Reading Mail section, click Unread Mail.
Click OK.
