Remove Duplicate Emails in Outlook

If you download emails from POP3 accounts or synchronize Outlook with
your PDA (Palm or Windows CE Device), you would have faced a problem of
too many duplicate emails in your Inbox. It is rather tedious and takes
lot of time finding duplicates manually and then deleting hundreds of
messages by hand. Outlook doesn't provide any built-in feature to to
find and delete Outlook duplicate email messages from one or several
Outlook folders.

While searching for tools to delete duplicate emails from Outlooks, I stumbled upon a completely free tool , Outlook Duplicates Remover,
that does exactly what it is supposed to do - Removes duplicate items
from Calendar, Tasks, Contacts, Notes, and mail folders in Microsoft
Outlook.

There's also a nice piece of Outlook VBA code that does
not actually delete the contacts, just flags them as duplicates. View
the Outlook VBA script.
Copy the script, then start up Outlook and choose
Tools->Macro->Visual Basic Editor. Paste all the text into that
window. You now have a VB script in your Outlook session called
"deleteduplicatecontacts". Open up the Contacts folder, choose
Tools->Macro. You will be prompted for which script you want to run.
Choose the "deleteduplicatecontacts" script and off it will go.

Microsoft also has a KB article on How to remove duplicate imported items in Outlook 2002, Outlook 2000, Outlook 98
