Hi there! It sounds like you're having some trouble with your mail merge in Word. I'd be happy to help you out.

It's possible that the font issue is being caused by the formatting of the Excel list you're using for the merge. Here are a few steps you can try to fix the problem:

1. Open your Excel list and select all of the cells containing the data you want to merge.
2. Right-click on the selected cells and choose "Format Cells" from the context menu.
3. In the "Format Cells" dialog box, click on the "Font" tab.
4. Make sure the font is set to Times New Roman and the size is set to 12 pt. Click "OK" to close the dialog box.
5. Save your changes to the Excel list and close the file.

Now, when you perform the mail merge in Word, the font and size of the merged text should match the formatting you set in the Excel list.

If that doesn't work, you can try downloading and installing the Times New Roman font on your computer. Here's how:

1. Go to the Microsoft Typography website and click on the "Download" button next to the Times New Roman font.
2. Save the font file to your computer.
3. Double-click on the font file to open it.
4. Click "Install" to install the font on your computer.

Once the font is installed, you should be able to use it in your Word document and it should stay consistent throughout the mail merge.
