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.
