How can I set Times New Roman as the default font for all users in my company?

If you want to enforce the font change, getting familiar with GPO is key. You might need to set up a policy that changes the default font in Microsoft Word and PowerPoint. I recommend checking online for specific guides on how to do that!

It sounds like your manager has a pretty big ask! The rationale behind this is likely to keep all communications standardized. If you're using Microsoft 365, a better way might be to create templates in the organization's asset library, ensuring everyone meets the style guidelines.

To be honest, sometimes you just have to push back on requests like this. Is there really a strong reason to enforce one font across everything? It could limit creativity and personal expression in communications.
