Sorry, but it’s not clear to me what is the difference between cleaning up CONVERSATIONS & cleaning up a FOLDER? Both refer to duplicate emails in the folder. Isn’t it the same thing?

The backup tool says it applies to Outlook 2007 and earlier, but your article is for Outlook 2016. Have you tried this tool and procedure on 2016?

I have tried your recommendations for cleaning up email folders in Outlook 2016. I always get the message that first that “No messages were cleaned up” followed by “Only messages that satisfy your Clean Up Settings will be moved to the “Trash” folder”. No matter what settings I choose no messages are cleaned up. Can you please advice me?

Clean up folder does not remove all duplicates from inbox. Is there another utility that does. I am getting emails in 4-to-6 duplicates at a time. At best the clean up function removes 2 duplicates.

How Duplicate Email Remover for Outlook works
Duplicate Email Remover is a flexible wizard that searches and processes duplicated email messages in Outlook folders. You can search different folders or find e-mail copies within the same folder using this helpful tool.
Duplicate Email Remover is just as configurable when it comes to handling the detected duplicates. You can choose to delete them at once, just flag them or move/copy to a special folder. So it gives you a chance to review the letters before removal.
The program is compatible with the latest Windows 10 and 8 and Outlook 2016 as well as Outlook 2013, 2010, and even 2007. Duplicate Email Remover for Outlook supports Microsoft Exchange Server and may be used to process public folders on the server
Delete, mark, copy or move duplicated emails to another Outlook folder
When this Outlook add-in finds duplicate messages, you can choose from a number of options to deal with the copies:
Delete duplicate (move to the Deleted Items folder) - a copy is moved to Deleted Items
Delete permanently - removes the copies without the possibility to restore them
Mark with a flag
Move to folder… - duplicates are transferred to the specified folder
Or Copy the found duplicates to the designated folder.
Search in 1 or several Outlook folders and set priority
The second step of this plug-in for Microsoft Outlook 2016 - 2003 allows choosing the search mode. Scan for duplicates within one folder or find duplicates in two or more folders to guarantee duplicate-free Outlook.
You can take advantage of the add-in's priority system that lets you find duplicates located in several different folders. You can use the priority system to specify which of the duplicated e-mails stored in different folders should be considered a copy. The action you pick for the copies will be applied to the items from this very folder. For example, you want to find duplicates in the 'Important' and 'Other' folders. Then you can specify that the item from the 'Other' folder is the duplicate so it is the one you want to delete, move, or apply the selected option while the 'Important' emails are left intact.
Select message fields for comparison
When you search for duplicate messages, you can select the field by which the messages will be compared. It is possible to choose such fields as text, subject, sender name or E-mail, recipients, Internet headers, attached files, date and time of sending. You can use these options separately or in combination.
When too many copies of the same message complicate your correspondence, choose Duplicate Email Remover for Outlook for easy de-duplicating process.
