When you make a mail merge in a Word 2010 document, to be able to edit a single document, such as adding personalized text to a specific recipient's letter, and to avoid the potential paper waste of direct printing, users can merge the letters into a new document first, as described in the following procedure:
Step 1th, open the Word 2010 document window and switch to the mail ribbon. Click the Complete and Merge button in the Finish group and select Edit Single document from the Open menu, as shown in Figure 2011080701.
