When creating a merge document, it is possible for users to experience mail merge fields changing font when merging.
Try each of the following steps in order until the issue is resolved:
1. Open the merge document through the parameter file (not the finished product document). 2. Highlight all the merge fields at once. 3. Select Styles and Formatting from the Format menu. A window appears showing the current format. 4. Select the 'Normal' formatting to each of the merge fields. 5. Re-run the merge.
* If using Microsoft Word 2007, use ALT+CTRL+SHIFT+S to access Styles. They can also be added to your toolbar by using the Customize Quick Action Toolbar.
