Outlook Duplicates Remover To Delete All Duplicate Items in Outlook


Microsoft Outlook is a mail client application that stores all the personal information such as contacts, notes, calendars, etc., besides; the mail in a PST files (Personal Storage Table). A PST file is the personal file of Outlook and is either found in ANSI or Unicode format. When more mails come up, there occurs an increase in the size of PST files, which leads to the slowdown of Outlook. So, Outlook is provided with the feature of PST file ‘Archive’, which stores the mails that are not recently used but, are still important to the user. Other root cause that contributes to the size increase of PST file is “Duplication” and for de-duplication there are no provisions in Outlook.

Duplication can occur because of either virus, improper implementation of POP3 settings, firewall or anti-virus, application of rules, etc. There are even other causes for duplications such as re-installation or re-configuration of Outlook, synchronization of Outlook with PDA, etc. The question is “how to get rid of the duplicates from the PST files?”

The size of PST files increase when duplication takes place. It is possible to remove duplication manually but, the problem is that during manual configuration there is a chance of losing the original PST file by mistake also, manual procedures are time consuming and tedious.
