Developer's Description

Outlook Duplicates Remover is an amazing tool that helps to remove duplicates from MS Outlook mailbox components including emails, calendars, tasks, contacts, etc. The tool offers dual ways for removing duplication of components and this includes removing duplicates within the folder and removing duplicates across folders.

The tool also offers an option to remove duplicates from Outlook OST and BAK files. Along with that, it offers to add either multiple files or a folder to the panel of the tool for implementing duplicates removal operation. Duplicates can be removed from selective mailbox components by checking the checkboxes available with each component. After performing the deduplication process, the resultant file can be stored anywhere on the machine or local storage media. Once the tool initiates the process, the overall status of the running operation is displayed within the tool panel. After completing the process, the software generates a complete report in CSV format. When the duplicate items have been removed, the PST file size reduces to a greater extent and this helps saving time as well as in better data management.

There is no file size limitation imposed on the file and the tool supports both ANSI and UNICODE type PST files for removing duplicate items. The tool also gives an option to choose multiple field option during the deduplication process. It comes with a trial version that allows exporting 15 files per folder. And in order to avail the complete functionality, you need to upgrade to the licensed version which costs only $29.
