Manually Remove Duplicates from Outlook 2003 and up
To remove duplicates, you need to use a single line table view.
In an email folder using the default group view, click on the row of field names and deselect Show in Groups, then turn off the Reading pane or slide it to the right.
For email folders, all standard views use a table view and you just need to turn off grouping and move (or turn off) the reading pane to enable the single line view. In the calendar, choose Events or By Category view, or in Outlook 2010, the List view.
- Right-click any column heading, then choose Field Chooser.
- In the Field Chooser, switch from the Frequently-used fields list to Date/Time fields, and then drag the Modified date field to the view to add it to the fields displayed.
- Click on the Modified column header to sort by that field.
- You should now see your Outlook items in reverse chronological order.
- Click on the first item you want to delete.
- Use the scroll bar to find the last item with the same modified date.
- Hold down the Shift key as you click on the last one. This selects all the items between the two selections.
- Press Delete to remove them all from the folder.
- Reset the view when finished.
This method works well with imported items or when you re-download messages left on the email server because you'll have one set of items with the same modified date.
