How to get rid of duplicate e-mail messages in Outlook 2007 – 2000

Today we’ll dig deeper into the problem of saving the user from Outlook duplicates, this time we’ll focus on deleting duplicate Outlook e-mails. Though, at first sight this problem may seem far-fetched, believe me, it’s not only users of various mobile devices trying to synchronize them with their desktop systems that have felt this dilemma in full measure on their own back, it also concerns thousands of ordinary Office users who were faced with incorrectly set e-mail servers. Whatever simple the solution may seem, it’s not possible to get rid of duplicate Outlook e-mails without deleting every single e-mail manually. In fact, it is not surprising at all. What seems ridiculous is that the fewer Office capabilities you use, the fewer problems you run into. As to our today’s subject, this statement is true as never before. The majority of Outlook plug-ins that we are going to review may appear very familiar to you. Absolutely right, some developers decided not to invent the bicycle, but rather create a few add-ins on the same platform, separate their functionality and sell them as separate products. “Brilliant” idea! From the user’s point of view, I don’t agree with this approach at all. It’s not the point that you have to pay extra money for each separate plug-in, it’s just that you have to install and come to know the particulars of two or more plug-ins instead of one. In my opinion, it would be more logical to create one add-in that works with all duplicates in Microsoft Outlook: in contacts, e-mails, appointments, personal and public folders. However, let it be on developers’ conscience (they also have to earn their leaving anyway) and let’s go on to reviewing plug-ins that will help you eliminate duplicate e-mails in Outlook.

Duplicates Remover for Outlook homepage

This Outlook plug-in from MAPILab purposed for finding and removing duplicate Outlook e-mails is a complete copy of the Duplicates Remover for Outlook (from our last week review) with regard to its user interface. The only difference is that options for working with e-mail folders are enabled. Now, in details:

A typical for MAPILab plug-ins installation wizard asks you to choose the installation type: for current user or for all users, and select languages (Russian, English and German are available):

Choose language

It also gives you the opportunity to learn beforehand where to look for the add-in’s toolbar in Outlook:

Add-in location

If you don’t have a registration code, you can freely use the plug-in in the trial mode:

Installation complete

The trial’s limitations are 30-day evaluation period and the ability to process up to 10 e-mails at a time.

A click on the Duplicate Email Remover toolbar brings up the first screen of the wizard indicating that the plug-in is ready for a new task:

Creating a new task

The About Program button shows your current version, the number of trial days left and the technical support service address:

About the add-in

At the first step, you decide whether to search for Outlook duplicate emails in each individual folder or in a group of folders.

Choosing the mode of search

At step 2, you select Outlook folders to be searched for duplicated messages. Although in the folders tree, you can also see the Contacts, Calendar, Notes and other folders, they are grayed out and that is why cannot be selected. Only e-mail folders: Drafts, Inbox, Junk E-mail, Outbox and Sent are active:

Choosing mail folders to be scanned

The list of possible actions that can be done with duplicate messages is provided at step 3:

Choosing the action for found duplicates

The following actins are available: mark with the flag, remove to another folder, copy to some folder, move to the Deleted Items folder, delete permanently, mark as expired etc.

At the final step, you select the fields for comparison: sender name, recipients, internet headers, attached files, date and time of sanding.

Selecting fields for comparison

In case you missed something or want to make some corrections, just click on the Back button and you will be taken to the previous screen. If you did everything correctly, click Finish.

Final step

Found duplicate e-mails are shown in the next window:

Result management

The same as the Duplicates Remover for Outlook, the Duplicate E-mail Remover (which is, in fact, looks like its twin-brother) shows a list of found duplicate Outlook messages in the upper part and actions performed in the lower part of the window.

Email De-duplicator from LBE Toolbox


  • Microsoft Outlook 2000, 2002/XP, 2003;
  • Microsoft Windows 95, 98, NT, ME, 2000, XP, 2003, Vista.

Email De-duplicator homepage

This tool for removing duplicate e-mails in Microsoft Outlook is very much like Contact De-duplicator inspected in our previous review of plug-ins purposed for deleting duplicate contacts from Outlook with the only essential difference – Email De-duplicator searches for duplicated Outlook e-mails. If you didn’t read the previous review, I’ll repeat here the main aspects in brief.

The plug-in installs correctly and quickly and can be started from the Start menu or by clicking on its icon on the desktop. The first window informs you about some limitations of the trial version. The main limitation is processing only up to 20 items at a time.

The main window of the Contact De-duplicator looks like this:

LBE Toolbox Email De-duplicator: Main window

So, you select Outlook folders, set the e-mail options and choose the action.

As clear from the available e-mail options, the plug-in can find duplicate Outlook e-mail messages with the sane subject and first recipient, send datetime, size, sender and received datetime. You can check all these options or some of them. For me this approach seems very reasonable and flexible.

As you see in the screenshot above, all folders are shown in the Outlook folders tree, though only e-mail folders are active. This tool, as follows from its name, works with e-mail duplicates only. As to e-mail folders, you can select as many as you like, and the plug-in will search for duplicate Outlook mails in all selected folders.

E-mail De-duplicator cannot boast with the high speed of work, so the more e-mails you have in selected folders, the longer you’ll have to wait. Some Outlook e-mail messages are processed in less than a second, others require 1- 2 seconds. The result of search is presented in a log:
LBE Toolbox Email De-duplicator: Found duplicate e-mails

One more thing you should be aware of is that the Email De-duplicator cannot be started from Outlook since it is not the add-in in its full sense. You can create a shortcut for the desktop or for the Quick Launch toolbar. Its item in the Start menu will be created in any case. The Email De-duplicator doesn’t have a comprehensive Help system, but this plug-in is so simple that you will hardly need any.

No More Dupes from Wisco


  • Microsoft Outlook 2000, XP, 2003;
  • Microsoft Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000, WindowsXP

No More Dupes homepage

All functions if this plug-in were thoroughly analyzed in our previous review of plug-ins that remove duplicates from Outlook contacts.(link) So, now we are going to have a look only at how it copes with removing Outlook e-mail duplicates.

In the main window, you select Outlook folders:

Select folders for search

After you click on the Search duplicates button, selected folders will be searched for duplicate e-mail messages. The result of search is shown in another window:
Remove found duplicates

All first occurrences are colored in blue (see the screenshot above), duplicate messages are ticked off for deleting.

No More Dupes doesn’t provide many settings. In fact, it doesn’t offer any :-) but for selecting folders for search, but this plug-in is able to find any duplicated Outlook messages in case they are totally identical.

Anti-Dupe for MS Outlook from Lookout Software


  • Windows 2000, XP, 2003, Vista (Microsoft .NET Framework 1.1 or higher required).
  • Microsoft Outlook 2000, 2002 (XP), 2003 or 2007.

Anti-Dupe for MS Outlook homepage

This free tool was also examined in the last week’s review (and delivered rather poor results, it should be admitted). Now let’s check how it works with duplicate Outlook e-mail messages.

So, in the add-in’s main window, tick the appropriate folder type:
Lookout Software Anti-Dupe for MS Outlook: Main window

Then select the folder that you want to search for duplicates:
Lookout Software Anti-Dupe for MS Outlook: Select the folder

Yes, only one folder can be selected at a time. In case you have duplicated messages in different Outlook folders, this tool will be of little use. The following result was received for duplicate Outlook e-mails that were in the Inbox folder only:

Lookout Software Anti-Dupe for MS Outlook: Search results

Summing up, it can be said that Anti-Duple for Microsoft Outlook works with Outlook e-mails as awfully slowly as with Outlook contacts. So, in practical work this Outlook plug-in is, in fact, of little to no use.
