Duplicate Email Remover finds and removes duplicates email everywhere you need
Search for duplicates in single Outlook folder
Search for duplicated emails across multiple Outlook folders
Search across Exchange mailboxes, public folders and IMAP accounts
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.

I have been using MAPILab Duplicate Email Remover since 2008. Every few years I reformat my computers and need to clean up all my Outlook emails and PST files. Your software has been a valuable addition to my software toolkit and has done a fantastic (and quick) job of cleaning out the extra junk. Thanks for a great product!
Question: I have around 500 duplicate emails in Outlook. I selected the default settings for everything and it says it scanned all ~12000 emails but found no mail duplicates.
You can see 8 search criteria in the step 4 of 4 of the ‘Duplicate Email Remover’ wizard - and 3 criteria are critical: "Text", "Subject" and "Sender E-Mail" are the basic fields in the process of recognizing duplicated messages in Outlook folders. If messages have different values in any of these fields -- they are not duplicates, according to common sense. Other, uncritical 5 criteria are active by default – but you can remove the checkmarks from these fields to relax the search process (one by one, in turn). In the most of cases, Internet Headers are different in messages even if they look like exact copies.
Question: I have run the Outlook duplicate email remover various times using various features and criteria. I have even run it on an individual folder and I can still see some duplicate emails despite it telling me there are no email duplicates in Outlook folder.
Answer: If the programme finds no more duplicates, in all probability no more exact copies exist. If reducing all 5 uncritical search criteria in the step 4 of 4 does not help - check your messages: an issue is known with some antivirus tools which add a unique stamp into the Outlook message body, and messages with differences in message text are considered to be non-duplicates in such a case.
Question: Your duplicates remover for Outlook works very well and I just have one issue: it is picking the wrong duplicate of 2 items – the more recent one. Is there a way we can get the add-in to pick up the older record?
Answer: Duplicate Email Remover analyzes the size and the date of Outlook items before processing - and it usually considers the larger email message is the "original" - and keeps it, and all smaller items are being processed as duplicates in such a case. Usually, the more fields contain data, the larger is the size of the item. If all the fields are similar (i.e. have the same size) – the duplicated mails remover add-in will consider the oldest item is the "original".
Question: I have two identical e-mail messages in an Outlook folder with one small but important difference between them: One has been replied to, so its "Icon" has an envelope with a purple "back" arrow. Of the two "duplicates," I strongly prefer to keep the one that was replied to-- however, your email duplicates remover saw it as the duplicate to be deleted. Can the add-in be made to keep "replied to" or "forwarded" messages over messages with no such action?
Answer: It looks like in your mailbox, unreplied message copies are older (or/and probably larger). But Duplicate Email Remover gives you a possibility to perform a search for duplicate items across the Outlook folders, and with the system of priorities. So, you can configure a regular Search Folder in Outlook, filter your messages by “Tracking Status”, move replied and unreplied messages to different folders, and then run Duplicate Email Remover over a group of your folders: you will be offered to set the prior folder in the 2nd step - and messages in it will be kept as originals.
Question: At the end of the search, the Outlook duplicate remover states it has found hundreds of duplicates, but I can still see them in my folders.
Answer: The Outlook add-in provides you with the processing report after completing comparison. Please expand it, or export to see its full version with the reasons: in order to process Outlook duplicates, our add-in requires full access permissions to the folders. If you process shared or public folders where you have limited permissions, processing duplicates might fail due to insufficient rights. Please contact your mail server administrator for full access permissions to those Outlook folders.
Question: After opening the application, choosing the mode of search in the step 1, and selecting "next," I get a pop-up Mapi Error.
Answer: In the step 2 of the add-in wizard, your Outlook folder tree is loaded to the add-in – and if it contains folders where you have limited access, or these folders are currently unavailable, the duplicate remover displays the errors. Usually, if you ignore such an error (it may occur as many times as many unavailable folders are there in the folder tree), the rest of you folders will be finally loaded, and you will be able to process them. If your folder tree is not loaded even after ignoring errors, please contact our support staff with the information about your Outlook version and account types.
