In Outlook 365, effectively managing your contacts is essential for smooth communication.

One way to enhance the visibility of your contacts is by increasing the font size.

To increase the font size of your contacts, consider changing the scaling settings on your computer.

For Windows users, you can do this by navigating to Start >> Settings >> Display settings >> Scaling.

Then, experiment with different scaling sizes to find the balance between making the address book easily readable and maintaining the right size for other texts.
