ODIR
Rating: 4
Version tested: 1.2.1
Description: ODIR is an add-on for Outlook that can detect duplicate items and move them to a special folder; these include contacts, appointements, tasks, notes, and emails (sent, received, and unsent). Does not work with Outlook Express.
I used this program with Outlook 2007 to scan around 18,000 emails for duplicates. Of these, approximately 10,000 were duplicates (after migrating my email from Thunderbird to Outlook, I somehow created 2 copies of 5,000 of my emails). Here are some notes on my experience with this program:
- Running the program: the installer creates an ODIR menu alongside Outlook’s original menus. Deduping begins when you select ’Remove Duplicate Items’ from this menu.
- How it works: items are considered duplicates if the following criteria are found duplicated: for contacts: first and last names, company name, and email address; for appointments: subject, location, start date, and end date; for tasks: subject, start date, due date and status; for notes: contents of the body and color; for emails/posts: internet message ID (for received email), email subject and the time sent (for sent email), and the subject alone for unsent emails.
- Effectiveness: it took about 4 hours for ODIR to sift through 18,000 emails. It was a processor-intensive affair and at times I found myself wishing that there was a pause button or even a mere indication that it was still chugging along and not crashed (the progress gauge was moving very slowly). No sooner than it was done, after about 4 hours, that it crashed. Fortunately it had already moved all duplicate emails into the ODIR_duplicate_items subfolder, and I was able to delete those. I speculated as to whether the crash was due to an incompatibility issue with Outlook 2007. In any case, the job was done.
I searched for a very long time for a free program that can detect duplicate emails in Outlook and I am very grateful that I found this one. In the end it did a very fine job.
Compatibility: A Windows machine that runs Outlook. Does not work with Outlook Express.

Any recommended programs to detect duplicate files on a hard drive?
I’ve been using Outlook Duplicates Remover (written by an ex-programmer / priest) for a couple years. It still works perfectly well with Outlook 2007, and it’s been quite stable.
It’s hard to find, but you can download it from a French site at http://objs.net/ODRsetup.exe

Any recommended programs to detect duplicate files in Outlook Express?
Great site man keep up the good work
Can you recommend a synchronization utility for Outlook & Outlook Express to be used on two or more different machines.
I could not find it work on my Outlook 2007 12.0.6023.5000 MSO 12.0.6017.5000 hungarian
Nothing has put into the menu of Outlook
Brian: Look for DoubleKiller by Big Bang. It’s a tiny program, it works incredibly well (I’ve used it to delete tens of thousands of duplicates and I’ve never seen it make a mistake), it sorts really fast, and it’s free. Just be aware that the free version does NOT delete to the Recycle Bin, so if you’re not sure about a file, you should use the program’s Move option instead of deleting.
Oops, just realized that someone already recommended DoubleKiller. Well, I second the rec. It’s one of my two favorite tiny utilities (the other is Cathy by R. Vasicek).
Also thanks to Cristos for posting the link. I’ve been looking for that app. I like it better than ODIR.
Alright, the app Cristos posted the link to wasn’t the one I was looking for. The one I like is Anti-Dupe for Outlook. Unfortunately, it’s no longer freeware, but I found an old copy. Worth looking around for it.
Doublekiller is a file dup, not an mail dup so cannot compare with ODIR.
Outlook Duplicate Remover at http://objs.net/ODRsetup.exe is a hidious thing. It doesn’t use indexing and compares each file with each other one. Fine if you only have a few to check but if you have 10,000, you’re looking at 100,000,000 file compares and weeks of processing.
We can see why he is “ex-programmer”
I installed ODIR on two rigs:
1. XP SP2 Outlook 2003
2. XP SP2 Outlook 2000
On the 2003 machine I get an error when Outlook loads at startup:
“object variable or with block variable not set
91
errorin clsContactInsp.CreateSharingMenu”
Which results in no ODIR on the menu. If I restart Outlook, ODIR appears.
On the 2000 rig, I installed ODIR, used it once to delete about 50 dupes, went back the next day and it’s gone from the menu completely- even with a re-start.
This is incredibly frustrating. It worked well once and I desperately need the functionality, but I can’t get the menu item back.
If anyone can offer any ideas, I’d appreciate it.
