Before You Start

Check first: Understand that the font changes you make using these steps will only affect *new emails* you compose and *your replies or forwarded messages*. They will not alter the appearance of emails you have already received, emails sent in the past, or emails composed by others. Also, ensure you are indeed using the Outlook desktop application, as the web version's settings are managed separately and this guide will not apply to it.

Quick Reference

Common Problems When You Set Default Font In Outlook

Even with clear instructions, you might run into a few common issues when trying to set your default font in Outlook. Don't worry, most of these problems have straightforward solutions.

Font Changes Don't Seem to Save

This is one of the most frequent problems. You go through all the steps, select your fonts, but when you open a new email, the old font is still there.

Recipients See a Different Font Than I Do

You've set a beautiful, unique font, but your colleagues tell you your emails look plain or use a different font.

Only Some Emails Use the New Default Font

You notice that new emails have your default font, but replies or plain text messages are still using the old settings, or vice-versa.

My Font Settings Reverted After an Update or Restart

Occasionally, you might find that your carefully set default font has mysteriously changed back to the old one, especially after an Outlook update or a computer restart.

Can't Find the "Stationery and Fonts" Button

A user might follow the steps but not see the specific button mentioned.

Advanced Tips for Setting Default Font in Outlook

Once you've mastered setting your basic default font, you can explore more advanced options to further refine your email appearance and efficiency. These tips can help you create a more polished and branded communication experience.

Leverage Outlook Themes and Stationery

While this guide focuses on fonts, Outlook offers entire themes and stationery options that include not just fonts but also backgrounds, colors, and graphics. You can find these options in the same "Signatures and Stationery" window where you set your fonts.

Consider Accessibility in Your Font Choices

When selecting your default font, it's not just about aesthetics; it's also about ensuring your emails are easy for everyone to read, including those with visual impairments.

Maintain Brand Consistency (Personal & Professional)

Your default font is a subtle but powerful part of your personal or professional brand. Consistent use across all your communications reinforces your identity.

Integrate with Custom Email Signatures

Your email signature is another key element of your email's appearance. It's important that your signature's font complements your default email body font.

Backup Your Outlook Settings (Advanced User Tip)

For advanced users or those who frequently customize Outlook, knowing how to back up your settings can be a lifesaver, especially if you move to a new computer or need to reinstall Outlook.

How To Set Default Font In Outlook FAQ

Q: Will setting a default font change the appearance of old emails in my inbox?

A: No, setting a default font in Outlook only affects new emails you compose, and your replies or forwarded messages that you send from that point forward. It does not alter the appearance of any emails you have already received, sent in the past, or emails sent to you by others.

Q: Can I have different default fonts for different email accounts within Outlook?

A: Outlook's "Stationery and Fonts" settings are generally global for the entire desktop application, meaning one default font setting applies to all accounts configured in that Outlook profile. However, you can create different email signatures for each account, and each signature can have its own specific font, size, and color. When you select an account to send an email, its associated signature will be applied, which can give the impression of different font settings.

Q: Why does my chosen font sometimes appear differently to my recipients?

A: This is a common issue. If your recipients do not have the specific font you've chosen installed on their computer, their email program will substitute it with a more common, generic font (like Arial or Times New Roman). To ensure your emails look consistent for most people, it's best to use widely available, standard fonts such as Calibri, Arial, Times New Roman, or Verdana.

Q: What is the best font and size for professional emails?

A: For professional emails, readability and professionalism are key. Common and highly recommended fonts include Calibri, Arial, and Times New Roman. These are clean, widely available, and easy to read. A standard size of 11pt or 12pt is generally considered appropriate. Using black text on a white background offers the best contrast and readability. Avoid overly decorative or script fonts for business communications.

Q: How do I revert to Outlook's original default font settings?

A: Outlook's original default font is typically Calibri, 11pt, in black. To revert to this, you would simply go through the steps outlined in this guide (File > Options > Mail > Stationery and Fonts) and manually select Calibri, 11pt, and black color for all three settings: "New mail messages," "Replying or forwarding messages," and "Composing and reading plain text messages." There isn't a single "reset to factory defaults" button specifically for font settings.

Q: Does this guide apply to Outlook on the web (Outlook.com) as well?

A: No, this guide is specifically for the Microsoft Outlook desktop application. Outlook on the web (Outlook.com) has its own separate settings, which are usually found under its "Settings" icon (often a gear symbol) and then navigating to "Mail" > "Compose and Reply" where you can set a "Message format" and "Font." The exact steps are different from those for the desktop application.
