HideOutlookFolders - Version 1.00 Outlook has many folders that you don't need, but can't delete. But with HideOutlookFolders you can HIDE them. Hide Inbox, Outbox, RSS Feeds, Sent items, Deleted Items, Drafts and more. Just a simple click and they'll be gone from the Outlook tree. This is extremely useful if you have several PST files and thus each folder several times in the folder tree. Now you can simply hide them from the Outlook folder tree. The folders still exist, but Outlook won't display the hidden folders any more.
