Recipient Experience Watch out for

Before You Start

Check first: When changing the default font for sending emails, your choice affects how every recipient sees your message. For professional communication, stick to standard, easy-to-read fonts like Calibri, Arial, or Georgia in a 10pt to 12pt size. Using overly large, small, or decorative fonts can appear unprofessional and may not display correctly on all devices.

Use Conditional Formatting to Make Important Emails Stand Out

Instead of making all text larger, you can make Outlook automatically change the font size and colour of incoming messages in your inbox based on rules you set. For example, you can make any email from your manager appear in a larger, bold font.

Create Quick Styles for Frequent Formatting Needs

If you often switch between different types of formatting within a single email (for example, a standard paragraph style and a highlighted "Action Required" style), you can save these as Quick Styles.
