When you import items into Microsoft Office Outlook and you add the contact as a duplicate, or if duplicate detection is turned off, there is not an option to remove duplicate items after you import. This could happen if you have moved your Outlook from computer to computer and imported your old PST file into new Outlook. Suddenly you may end up with duplicate emails, contacts or calendar items. There is existing Microsoft KB article on this issue and has all steps covered how to do it manual way. I have found 2 interesting FREE and PAID tools to fix this problem easy way.
