Conditional formatting in new Outlook and web

Conditional formatting is a feature designed to highlight important emails based on certain conditions defined by the user. These conditions can be related to the message sender, subject line, or the presence of your name in a particular field. By applying different colors, you can quickly identify messages that require your immediate attention without sifting through less pertinent ones. Conditional formatting in the new Outlook and web

How to use Outlook conditional formatting to highlight emails

In the new Outlook app and Outlook on the web (the online version for users with a work or school account), the process of setting up conditional formatting is essentially the same. There might be slight differences in the interface elements, but the core steps remain consistent across both platforms.

To create a conditional formatting rule for color-coding emails in the new Outlook and web, follow these steps:

  1. Access the conditional formatting settings. Click the Settings gear icon in the top-right corner, and then go to Mail > Conditional Formatting.
  2. Choose account. If you have multiple accounts in the new Outlook, ensure that the correct one is selected (by default, it will apply to the primary account). If you have just one account or are using the web version, skip this step.
  3. Add a new rule. Click + Create new conditional formatting rule to begin setting up your rule. Create a new conditional formatting rule in new Outlook and web.
  4. Name your rule. In the first box, type a name that will help you identify the rule later. Name the rule.

    • From specific people
    • Your name is / is not on the To or Cc line.
    • Subject includes certain text.

    If you need more than one criterion, click + Add another condition and then define the additional criteria. Define the conditions.

  6. Choose the format. Click the Choose Color button, and then pick the font color for your rule. The Preview section will display how the text will appear with the chosen formatting. Choose the format.
  7. Save the rule. After setting up your conditions and formatting, click the Save button to apply the changes and save your new rule. Save the rule.

By following these steps, you can highlight critical emails in different colors, making them easily identifiable in your mailbox folders.

This feature allows you to adapt your email management strategies on the fly and maintain control over your inbox organization with minimal effort.

How to change the rules order

The order of conditional formatting rules in Outlook is important, as they are applied sequentially from top to bottom. Higher listed rules take precedence over lower ones, which can affect how emails are highlighted in your Inbox and other folders.

For example, let's say you have two rules:

  • Rule 1 highlights all messages from the admin in blue.
  • Rule 2 highlights all messages with the word "important" in the subject in red.

If Rule 1 is listed above Rule 2, then all messages from the admin will be highlighted in blue, including those with "important" in the subject. However, if Rule 2 is above Rule 1, messages from the admin with "important" in the subject will be highlighted in red instead.

To adjust the order of the rules and thus change their priority, you can use the Move Up and Move Down buttons provided in the conditional formatting settings: Change the order of conditional formatting rules in the new Outlook.

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.

Examples of conditional formatting

Here are some practical examples of how you can color code your emails with conditional formatting in the new Outlook:

  • Highlight messages from VIP clients in red. This will make emails from top-priority clients immediately noticeable.
  • Emphasize emails with specific keywords in the subject. For instance, if you're working on a project named "Orion," you can set a rule to highlight all emails with "Orion" in the subject line.
  • Distinguish emails from your manager or direct reports. Set a rule to color-code emails from specific individuals, such as your manager or team members.
  • Mark emails related to upcoming deadlines or events. Use a distinct color to highlight emails with upcoming dates or approaching events mentioned in the subject line.

Limitations and differences of new Outlook conditional formatting

While conditional formatting in the new Outlook and web offers several benefits, it's important to be aware of its limitations and differences from the classic desktop Outlook application:

  • Availability. It is only available for Microsoft 365 work or school accounts in the new Outlook and the web version.
  • Scope of application. A conditional formatting rule applies to both read and unread messages across all folders, except Drafts.
  • Fewer conditions. Compared to classic Outlook, the new Outlook and web have fewer options for conditions.
  • Limited to emails. In the new Outlook and web, conditional formatting is currently available only for emails, not for calendar items and tasks.
  • Formatting options. The only formatting option available is changing the font color of emails. Other formatting styles such as font type or size are not supported.

By understanding these limitations, you can better tailor your conditional formatting rules to suit your needs.

Hopefully, this guide on new Outlook conditional formatting has equipped you with the necessary skills to effectively color-code your inbox, ensuring that important emails beckoning your attention will never go unnoticed.

  1. I have the same issue. This is in the "Conditional Formatting", in the "condition" section where there is no "To" under "People".

    • Hello Lambert,

      The new Outlook's Conditional Formatting has the option "I am on the To line" - please see the screenshot under "Step 5. Define the conditions" in this tutorial. The option to highlight emails where I am the only one in the "To" line is missing indeed.

  2. I am missing an important option which I used a lot in the classic Outlook - The option the mark emails where I am the only one in the "To" line.
    I find it the most useful since I can priorities emails sent to me directly.
