Free, Fast and easy tool for removing duplicate items from Outlook folders

With ODIR it's a snap to clean your Outlook folders by removing all duplicates. ODIR removes duplicates from Contacts; Calendar; Tasks; Notes and Email folders.

 

Using ODIR is very easy: select a folder and click the button Remove Duplicate Items. ODIR scans the selected folder for duplicates and MOVES all duplicates found to a subfolder ODIR_duplicate items.

• Contact items:
  first name, last name, company name and email address
• Appointment items:
  subject, location, start date and end date
• Task items:
  subject, start date, due date and status
• Note items:
  contents of the note (Body property) and color
• E-mail or Post items:
  - received emails: the internet message ID (this is a unique identifier for each email received)
  - sent emails: email subject and the time the email is sent (PR_CLIENT_SUBMIT_TIME)
  - unsent emails: email subject only
