How can I remove Duplicate Emails from Outlook for Free?
I have used many different email addresses in my 10+ years on the Internets. I started with a email address from Brooklyn College, moved on to Hotmail and then several custom domains. I would ping-pong between different corporate emails and amusingly geeky personal ones. But being an Admin by profession I have kept all my craptastic forwards geektacular jokes “Historical Emails”.
I have folders with email messages dating back to 1996. Now I try and stay neat and productive, creating necessary folders for projects or contacts. Archiving when I no longer need instant access to outdated material. But that just doesn’t happen when I am putting out fires around the virtual office all day. And the end result is a inbox full of CRAP! Looking through some of my older emails I found loads of duplicates and for some reason that REALLY annoyed me.
I went looking for a FREE Outlook Duplicate Remover. Easier said then done. All the ones I downloaded were crap-ware. Pure Trial Crap. Trial software is like what Crack is to the drug market. Give them a taste for free, let them see what we can do and then get them hooked. After you are hooked yank it away and ask for money.
But as always I did find what i was looking for - for free. It’s called Vaita’s free Outlook Duplicate Items Remover.
Guess what it does?
Wow, you MakeUseOf readers sure are smart! It removes duplicate items from Outlook! I tried it on Outlook 2003 and it says it works with all versions of Outlook 2000, 2002, 2003 or 2007. I do not see that it works with Outlook Express.
Let’s check it out and I will show you how easy it is to use! After downloading and installing the small 2.11MB File you will be prompted to shut down Outlook to complete your installation.
Upon restarting Outlook you will have a new menu item as you can see below:
Once you click on the ODIR menu Or Hit Alt-O you will be greeted with it’s menu allowing you to simply select what folder you want to run ODIR against. You can do sub-folders but not all the way at the Personal Folder level. Meaning you might have to run this several times against several different folders.
In the instance above I selected a folder in by inbox labeled Sonicwall Alerts. All I do is hit the Remove Duplicate Items button and let the app do it’s magic.
Depending on the amount of messages or items in that particular folder is how long it will take. A folder with a hundred messages will take 30 seconds on a fast machine and a few thousand emails will take a few minutes. Once it finds the messages it creates a sub folder called ODIR_Duplicated_Items and moves the dupes there.
You can then decide if you want to /kill the folder or just individual items. As you and ODIR build a better relationship and you come to trust her… You can just have the folder disappear automagically.
I hear you muttering why did I say items and not messages in that last paragraph… That’s because this will work on Contacts, To-Do Items and Calendar entries! How sweet is that? Undo the damage you did syncing your new device! Are you curious as to how ODIR Works it’s magic? Check out this:

I don’t care much about dupe emails… but contacts? Dear God, someone please help me de-dupe my Outlook contact list!
I had to get all the way to the end to discover in the last screenshot that it de-dupes contacts as well! But maybe there are better ways? I’d love an interface like the genealogy programs I use that let you pick and choose which fields to keep from each dupe before merging.
To put it bluntly: it doesn’t work for Appointments in Outlook 2007. I suppose it doesn’t work for other parts of Outlook 2007
For me this program helped a lot - http://www.topalt.com/deduper-outlook-duplicate-remover
Thanks so much! It worked REALLY well to help me clean up duplicates created by my Palm’s hotsynch escapades. It worked a bit more trouble free when I turned off Google Desktop.
It used to work for me with Outlook 2003 but it screwed up big time with Outlook 2007.
Used it with outlook 2007 and i am very pleased with the result.
Thanks for all the “research”!

vista sp1 & outlook 2007 sp1 -> worked great, no problem with this remover
THANKS SO MUCH! Been trawling Google for ages only to find hordes of shareware. This little app did the lot, and not once asked for a penny. I am so grateful to MakeUseOf and “vaita”… WELL DONE GUYS!
Thanks bud
You saved my a*s big time
Matt South Africa
You saved my hours.
Thanks
Great advise, thanks.
thanks!! just got read of 2500 duplicates!
It doesnt work in the “deleted” folder either. I think its because this folder is a mix of sent and received emails and the app doesnt know what to do with them. Ah well, does work in other folder OK though, but the Sent folder it finds duplicates that are not really dups.
Its the deleted items folder!! Delete them!! Why do people continue to hold email in the deleted items folder. Sorry pet peave… some goes for Notes as well.
PS. This program 100% in Outlook 2007 for my Inbox.
Hi there!
Thanks a lot for finding and reviewing this gem. Saved me a whole lotta time and effort.
Regards
Doesn’t work on Outlook 2007
most awesome dude…
Worked perfectly with Outlook 2007 in Exchange 2003 (SBS 2003) environment. Removed 32767 duplicate emails from just one folder and this was quite legitimate. Was very slow, but expected given the size of this users mailbox and the number of duplicates that were glaring obvious.
Outlook Duplicate Items Remover is GREAT! Thanks Vaita.
This is really a great tool. Thanks. I will share it with all my friends and social networks like friendfeed.
Thanks Alot for this article. This is my life saver…. was able to remove all the duplicate emails my stupid server had POP’ed when had leave a copy on server… This works great!!
If you are having problems in Outlook 2007, try moving your emails to Personal Folders and running it in Outlook’s Offline Mode. The problem seems to be when it is trying to connect to the Exchange Server.
