Hi Jeremy,
I understand you are using the save as option to save the document to PDF and the border disappears in the converted PDF.
May I know if changing the size of the paper makes the border appear in the resulted PDF? Just for the test purpose please use Print option to convert doc to PDF, check whether border appears or not. This is just to confirm if border is invisible when printing to PDF or only the Save as option causes this issue.
Besides, please check if your Office apps are fully updated. The latest version of Microsoft 365/2019 for mac is 16.50 (21061301). To check the version, open any Office app such as Word, go to the Word menu and choose About Word.
If the version appears lower, then manually update Office apps, click Help > Check for Updates from any of the Office apps to get the latest build.
If the issue persists, please provide the following information:
- Please confirm the version and build of Word for Mac. To get this information, open Word, go to the Word menu, and choose About Word.
- Open file in Preview app and convert it to PDF, check if it shows the same result.
- May I know if adding border to another document and converting it to PDF have similar behavior?
Regards,
Neha
