If you want to change the status of a rejected match, start by changing the filtering to show only rejected matches and reducing the number of stars to zero.
Now that you have all rejected matches in one place there are three ways you can undo the reject.
1. Review the Record Matches individually and use the “Undo Reject” option.
2.Use Confirm All at the bottom of the page (this will only confirm the matches on the page you’re looking at, if you have more than one page of matches you want to Confirm All for each page).
3. When viewing the list of rejected matches, click the X to undo the rejection and set the match back to pending or click the √ to change the match status to Confirmed.
