Do you have email duplicates located in the same folder as the original message? Select the folder or use the "all folder" option and the product will analyze each folder separately for duplicates and process the folders one by one. Do you have duplicated mail messages disseminated into several Outlook folders and you do not know how to detect them? Duplicate Email Remover will do this job for you. In the mode "across folders search" the product analyzes all selected folders first and then processes duplicates in the second step. The folder priority list allows you to choose the folders which should be considered the "source" of the given messages and which folders contain "duplicates" to be processed. Duplicate Email Remover allows you to process all types of folders and mailboxes in Microsoft Outlook. If you are using a Microsoft Exchange account or if several such accounts are connected to your Outlook, the product will do the job properly. Even if you need to delete duplicated emails in Public Folder on Microsoft Exchange Server or in an external account connected to Outlook (for example, a GMAIL.COM account connected via IMAP) — Duplicate Email Remover is the solution!

Reasons to remove duplicate emails from Outlook folders regularly:

 Answered or forwarded emails are marked with a special icon in Outlook folders, but the duplicates are not. Did you answer this message or not? It is a secret.

 Duplicated emails and posts in trash folders occupy space in the Outlook Data File (PST) and slow down Outlook speed and productivity.

 Extraneous duplicates in the folders complicate and decelerate data indexation and search in Outlook.

 More space is required to archive and backup data.
