Save the main document and the recipient list will be retained; or save the comprehensive document, which includes each merged copy.
If you plan to use the main document again for another mail merge, it's a good idea to save it. Saving the main document means that you will keep the connection to the recipient list. When you open the document again, you will be asked if you want to connect to the same list.
To save the document:
Click the Microsoft Office Button
On the menu, click Save
. Then choose a location and name for the file and click Save
Note If you used the Edit Individual Documents option, you can save the separate, comprehensive document also, but keep in mind that it's going to be a larger file.
