Using Outlook for Android for personal email and calendar management
Hi,
Please try to change the default font and size in Outlook on the web.
- Please make sure that you close your Outlook app on your phone.
- Go to Outlook on the web and open Settings (gear icon), then go to Mail > Compose.
- Under Message format, you can customize your preferred font, size, and text style.
- Click the drop-down arrow beside the font size to view all available font sizes.
- After making your changes, select Save at the bottom of the page to apply them.
- Open the Outlook app on your phone and check whether the changes took effect.
If it does not change, try changing your phone's display font size.
If it still doesn't change, please log out of your account, then log back in.
If it is still the same, please try clearing the cache and data of the app. Please note that this will log you out of your account in the Outlook app.
If you need additional assistance, please let me know.
I look forward to your response.
