Outlook Duplicate Item Remover (ODIR) is, as its name suggest, a software created to remove duplicated items in Outlook Express. That kind of task can be performed quickly and easily.
ODIRwas mainly created to detect items that are repeated twice or more. This could be, for instance, the contact items such as name or addresses, the appointments items like the subject or the location, or the text itself.
After detecting the duplication, the software proceeds to delete those files rapidly. For that, the user only has to choose the folder where they want to look for duplicates and click the Remove duplicated items button.
The advantage with ODIR is that it is compatible with all version of Outlook except the 2013 one. The user has just to install the software and it automatically works with the Outlook Express already installed on the computer.
Please note that ODIR does not support running in Outlook 2013 and in 64bit Office version.
This software can be downloaded and used for free.
