Email text emphasis in Outlook helps readers focus on critical information within messages. Learning how to highlight in outlook email can transform your communication from cluttered to crystal clear. Whether you’re flagging action items, marking deadlines, or simply drawing attention to key points, highlighting makes your emails more effective.
Many users think highlighting in Outlook is complicated or requires special add-ins. The truth is simpler. Outlook offers several built-in tools for text emphasis, and most are just a few clicks away.
This guide covers every method you need. You’ll learn the quickest ways to highlight text, format messages for maximum impact, and avoid common mistakes that make emails look unprofessional.
Why Highlighting Matters In Email Communication
Highlighting isn’t just about making text look pretty. It serves a real purpose in busy inboxes. When recipients scan dozens of emails daily, highlighted sections grab attention instantly.
Consider this: research shows people spend an average of 13 seconds reading each email. That’s not much time to convey your message. Highlighting helps you make those seconds count.
Key benefits of highlighting in Outlook emails:
- Draws immediate attention to action items
- Helps readers locate deadlines and dates quickly
- Reduces the chance of important details being missed
- Makes your emails more scannable and reader-friendly
- Improves overall response rates for requests
Highlighting works best when used sparingly. Overuse dilutes its effectiveness. Reserve highlights for the most critical pieces of information.
How To Highlight In Outlook Email
Now let’s get into the practical steps. This section covers the most common methods for highlighting text in Outlook emails. Each method works slightly differently, so choose the one that fits your needs.
Method 1: Using The Highlight Button On The Ribbon
This is the most straightforward approach. The highlight button sits right on the Format Text tab in Outlook’s ribbon menu.
Follow these steps:
- Open a new email or reply to an existing message
- Click inside the message body where you want to add text
- Type your text, then select the words you want to highlight
- Go to the Format Text tab at the top of the window
- Look for the Text Highlight Color button (it looks like a marker pen)
- Click the button to apply the default yellow highlight
- To choose a different color, click the small arrow next to the button
- Select your preferred color from the palette
That’s it. The selected text now appears with a colored background. This method works in both new messages and replies.
One thing to note: the highlight button only appears when you’re composing an email. You won’t see it when reading received messages.
Method 2: Keyboard Shortcuts For Faster Highlighting
If you prefer keyboard shortcuts, Outlook has you covered. While there’s no direct shortcut for highlighting, you can use a combination of keys to speed up the process.
Try this workflow:
- Select the text you want to highlight using Shift + Arrow keys
- Press Alt + H to open the Home tab in the ribbon
- Press F to access the Font options
- Press H to activate the highlight tool
- Use the arrow keys to choose a color, then press Enter
This sequence takes practice, but it becomes second nature after a few uses. For power users, this method is much faster than reaching for the mouse.
Another shortcut: after highlighting once, you can press F4 to repeat the last action. This applies the same highlight to newly selected text without navigating menus.
Method 3: Using The Font Dialog Box
The Font dialog box offers another way to apply highlighting. This method gives you more control over formatting options.
Here’s how:
- Select the text you want to highlight
- Press Ctrl + D to open the Font dialog box
- Look for the Text Effects button at the bottom
- Click it to open additional formatting options
- Select Text Highlight Color from the menu
- Choose your color and click OK
This method is less commonly used but can be helpful when you’re already adjusting other font settings like size or style.
Method 4: Highlighting In Outlook For Mac
Outlook for Mac works slightly differently. The highlight feature is still available, but the location varies.
Steps for Mac users:
- Open a new email message
- Select the text you want to highlight
- Go to the Format menu at the top of the screen
- Choose Font from the dropdown
- Click the Text Highlight Color button
- Pick your color from the palette
Mac users can also use the ribbon toolbar. Look for the highlight icon under the Message tab. It looks identical to the Windows version.
Method 5: Highlighting In Outlook Web App (OWA)
If you use Outlook through a web browser, the process is similar but with a slightly different interface.
Here’s what to do:
- Click New message to start composing
- Type your text and select the portion to highlight
- Look for the formatting toolbar at the bottom of the message
- Click the More options button (three dots)
- Select Text highlight color
- Choose your desired color
The web version offers fewer color choices compared to the desktop app. You’ll typically see about 15 colors instead of the full palette.
Advanced Highlighting Techniques
Beyond basic text highlighting, Outlook offers several advanced features. These can take your email formatting to the next level.
Using Conditional Formatting For Automatic Highlights
Conditional formatting is a powerful feature that automatically highlights certain types of emails in your inbox. This is different from highlighting text within a message, but equally useful.
To set up conditional formatting:
- Go to the View tab in Outlook
- Click View Settings
- Select Conditional Formatting
- Click Add to create a new rule
- Name your rule (e.g., “Urgent Emails”)
- Click Condition to set your criteria
- Choose the font color, size, or style for matching emails
- Click OK to save
Now emails meeting your criteria will automatically appear with the formatting you selected. This helps you spot important messages without opening them.
Highlighting With Tables And Shading
Sometimes you need to highlight entire sections of an email, not just text. Tables with shaded cells work well for this purpose.
Steps to create a highlighted table section:
- Click where you want the table in your email
- Go to the Insert tab and click Table
- Choose a simple 1×1 table for a single highlighted section
- Click inside the table cell
- Go to the Table Design tab
- Click Shading and choose your color
- Type your content inside the cell
This creates a colored box around your text. It’s more visually prominent than simple text highlighting and works well for callouts or warnings.
Using Text Boxes For Emphasis
Text boxes offer another way to highlight content. They float above the email body and can be positioned anywhere.
To add a text box:
- Go to the Insert tab
- Click Text Box
- Choose Simple Text Box or draw your own
- Type your content inside the box
- Use the Shape Fill option to add background color
- Adjust the border if needed using Shape Outline
Text boxes are great for side notes, important reminders, or disclaimers. They stand out from the regular email flow.
Common Mistakes To Avoid When Highlighting
Even experienced users make errors with highlighting. Here are the most common pitfalls and how to avoid them.
Over-Highlighting Everything
When everything is highlighted, nothing stands out. Limit highlights to 10-15% of your email content at most.
Good practice: highlight only the single most important point per paragraph. If you have multiple key points, use a numbered list instead.
Using Too Many Colors
Stick to one or two highlight colors per email. Using five different colors confuses readers and looks unprofessional.
Yellow is the safest choice. It’s the most visible and universally understood as a highlight color.
Highlighting Entire Sentences
Highlighting full sentences dilutes the effect. Instead, highlight only key words or short phrases.
For example, instead of highlighting “The meeting has been rescheduled to Friday at 3 PM,” highlight only “Friday at 3 PM.”
Ignoring Accessibility
Some highlight colors are hard to read for people with color vision deficiencies. Avoid red-green combinations.
Always test your highlights by viewing the email in plain text mode. The meaning should still be clear without color.
Highlighting In Outlook For Mobile Devices
Many people read and compose emails on their phones. The Outlook mobile app supports highlighting, though the interface is different.
For iOS and Android:
- Open the Outlook app and start a new message
- Tap and hold to select text
- Tap the Format button (A with a pencil icon)
- Scroll right in the formatting toolbar
- Tap the Highlight icon
- Choose your color from the options
The mobile version offers fewer formatting options than desktop. But basic highlighting works well for quick emphasis.
One limitation: you cannot highlight text in received emails on mobile. The feature only works when composing new messages.
Troubleshooting Common Highlighting Issues
Sometimes highlighting doesn’t work as expected. Here are solutions to frequent problems.
Highlight Button Is Grayed Out
This usually happens when you’re viewing a received email, not composing one. The highlight feature only works in compose mode.
If you’re composing and the button is still gray, try clicking inside the message body first. The button activates once you have an active cursor in the text area.
Highlight Doesn’t Show For Recipients
This occurs when the recipient uses a different email client that doesn’t support rich text formatting. Some clients display plain text only.
To ensure your highlights are visible, send a test email to yourself first. Check how it appears in different email clients.
Consider using alternative emphasis methods like bold text or asterisks for critical information. These work across all email clients.
Highlight Color Looks Different On Screen Vs Print
Screen colors and printed colors rarely match perfectly. Test your highlights by printing a sample if the email will be printed.
Stick to standard colors like yellow or light blue. These print more reliably than pastel or neon shades.
Best Practices For Professional Email Highlighting
Using highlighting effectively requires some strategy. Follow these guidelines to maintain professionalism.
Match Highlighting To Your Brand
If you’re sending business emails, use highlight colors that match your company’s brand palette. This creates a cohesive look.
Avoid bright, flashy colors in professional contexts. Subtle shades work better for corporate communication.
Combine Highlighting With Other Formatting
Highlighting works well alongside bold, italics, and underlining. Use bold for the main point, then highlight the most critical detail within that point.
Example: “The deadline for this project is Friday, June 15th.”
Use Highlighting For Calls To Action
Always highlight your call to action. Whether it’s a link, a date, or a request, make it impossible to miss.
Good examples of CTAs to highlight:
- “Please reply by
Wednesday “ - “Click
here to confirm attendance” - “Approval needed
before 5 PM today “
Keep It Consistent
Use the same highlight color for the same type of information throughout your email. For example, always use yellow for deadlines and blue for action items.
Consistency helps readers develop a mental map of your email. They’ll know what each color means without thinking.
