Highlight Important Emails with Conditional Formatting

Conditional formatting helps you spot important emails faster. You can set rules based on things like who sent the message, what’s in the subject line, or if your name is mentioned. Then, Outlook will automatically highlight those emails with different colors, so you can easily see which ones need your attention right away—without digging through all your other messages.

How to change the rules order

Why the Order of Conditional Formatting Rules Matters in Outlook

In Outlook, the order of your conditional formatting rules is important because they’re applied one after the other—from top to bottom. Rules at the top have higher priority and can override the ones below them.

Here’s an example:

  • Rule 1: Emails from the admin are highlighted in blue
  • Rule 2: Emails with “important” in the subject are highlighted in red

If Rule 1 is above Rule 2, then any email from the admin—even if it has “important” in the subject—will be blue.
But if Rule 2 is on top, then those emails will be red instead.

To change the order of your rules, go to the Conditional Formatting settings and use the Move Up or Move Down buttons.

By organizing the order of your conditional formatting rules, you can control which rules take priority, ensuring that your most important formatting criteria are applied correctly.

Limitations and differences of new Outlook conditional formatting

Things to Keep in Mind About Conditional Formatting in the New Outlook and Web Version

Conditional formatting in the new Outlook and the web version is a great tool, but it does have some limits compared to the classic desktop Outlook. Here’s what you should know:

  • Who Can Use It: It only works if you have a Microsoft 365 work or school account.
  • Where It Works: The rules apply to all folders, including read and unread emails—but not to Drafts.
  • Fewer Rule Options: The new Outlook and web version have fewer condition choices than the classic Outlook.
  • Emails Only: You can only use it for emails—not calendar events or tasks.
  • Limited Formatting: Right now, you can only change the font color. You can’t change the font style or size.

Knowing these limitations can help you set up smarter, more useful rules.

Hopefully, this guide helped you learn how to use conditional formatting in the new Outlook. With color-coded emails, it’s easier to stay on top of what matters—so nothing important slips through the cracks!
