In choosing an Outlook duplicate remover in 2026, I would look out for a software that can detect duplicates effectively, scan the selected folders, and give various options for the outcomes. The above-listed features will be more helpful when dealing with huge PST archives.

The software that I considered while choosing the right Outlook duplicate remover was Kernel for Outlook Duplicates Remover. This software can scan several PST files, search for duplicates in selected folders, find duplicates based on certain attributes like the sender, subject, date and time, message content, and attachments. You can also perform such actions as moving, copying, flagging, or deleting the duplicates. You will have a free trial period to try the software but you will only be able to remove ten duplicates from each folder.

Before selecting a particular software, it is advisable to backup PST files and consider if its features are compatible with your version of Outlook.
