Disappearing “Unread Mail” folder in Microsoft Outlook 2007

When using Microsoft Outlook 2007 you may find your “unread mail” folder mysteriously disappears from time to time – fortunately there is a quick way to get it back.
In the Mail Folders list, navigate to the Search Folders option under your Mailbox
Right-click the search folders and select New Search Folder. Under “Select a Search Folder”, the option “Unread mail” should be highlighted in the category “Reading Mail”. Click OK.
This will create a search folder for unread mail – now simply right click on this folder and select “Add To Favorite Folders” – the Unread Mail folder should now reappear under Favorite Folders.
