PCWorld described this customization in its September 22 Outlook tip, and Microsoft’s support documentation confirms Cc-based coloring as a supported use of conditional formatting. The useful detail is the condition: choosing a font color alone does not tell Outlook which messages should receive it. You must also select the criterion that identifies your address in the Cc line.
Microsoft’s current support page states that conditional formatting is available to people using a work or school account with a qualifying Microsoft 365 subscription. Although that page also contains Outlook.com instructions, those instructions should not be taken as a promise that every personal account exposes the feature. Check for the setting in the client and account you actually use before building your workflow around it.
Classic Outlook puts Cc formatting inside View Settings
In classic Outlook, conditional formatting belongs to the message-list view. Microsoft documents the path as View > View Settings > Conditional Formatting. That corrects the “View > View Options” wording in PCWorld’s September 22 tip.
The setup has two separate parts: the appearance and the matching criteria. Give the rule a recognizable name so you can find it again when changing colors or disabling the treatment.
- Open the View tab and, in the Current View group, select View Settings.
- In Advanced View Settings, select Conditional Formatting.
- Select Add and name the rule
CC Emails. - Select Font, choose a distinctive text color, and select OK to return to the rule.
- Select Condition to open the filtering criteria.
- On the Messages tab, enable the recipient-position condition and select the option indicating that you appear on the Cc line.
- Select OK in the Filter, Conditional Formatting, and Advanced View Settings dialogs to save the changes.
Microsoft documents the view path, rule creation, Font and Condition controls, and confirmation dialogs. For the Cc-specific selection, PCWorld describes a checkbox labeled “In Which I” and an option reading “I am listed with other recipients on the CC line.” Its tip was translated from German, so the precise wording may differ in your interface; the criterion you need is your own presence in Cc.
Do not enter CC as a subject keyword. That would identify messages containing those letters in the specified text field, which is a different test from whether you were copied on the message.
Classic Outlook already includes conditional-formatting rules. Microsoft specifically identifies Unread messages, which makes unread mail appear bold. Keep that existing behavior in mind when choosing your Cc treatment: color can provide an additional visual distinction without requiring you to repurpose bold text as the signal for copied mail.
New Outlook and Outlook on the web use a Settings-based rule
New Outlook for Windows and Outlook on the web expose conditional formatting through Settings > Mail > Conditional Formatting. Microsoft documents the same basic creation procedure for both interfaces, including a preview of the selected message-list font color.
For either interface, provided the setting is available for your account:
- Open Settings, then select Mail > Conditional Formatting.
- Select + Add rule.
- Enter a descriptive name, such as
CC Emails. - Under the condition selector, choose the option for being included in the Cc line.
- Select the font color and inspect the Preview.
- Select OK, then Save.
PCWorld’s earlier coverage of the Settings-based interface identifies the condition as “I’m on the Cc line.” That is the recipient-based option to look for, rather than a sender or subject condition.
Choose a color that remains easy to read against your Outlook background. The purpose is quick recognition, so a color that is merely bright but difficult to read works against the task. Microsoft uses orange for Cc messages in its examples, but that is an illustration, not a required choice.
There is an important scope difference to remember when checking the result. For new Outlook and the web interface, Microsoft says conditional-formatting rules apply to both read and unread messages, across all folders except Drafts. Reading a copied message therefore does not, by itself, remove its Cc formatting. Do not automatically carry that documented cross-folder behavior over to classic Outlook’s view-based setup.
Outlook rule order can decide which color you see
A message can meet several formatting conditions at once. An email from your manager might also contain a project keyword and include you in Cc. In new Outlook and Outlook on the web, Microsoft says rules are prioritized in their displayed order: when rules conflict, the higher rule wins.
That gives you a practical choice about what the message list should communicate first. If recognizing a particular sender is more important than recognizing copied correspondence, that sender’s formatting should take priority. If distinguishing Cc traffic is your main goal, arrange your competing rules accordingly.
To inspect the outcome, use a message whose recipient details visibly include your address in Cc. The expected change is its text appearance in the message list, not a change to its body. If the color is unexpected in new Outlook or the web interface, compare the rule’s condition and position with other rules that could match the same message.
The adjustment is reversible:
- In new Outlook or Outlook on the web, return to Settings > Mail > Conditional Formatting and use the toggle beside the rule to switch it off.
- In those same interfaces, use Edit to change its fields and Save to retain the changes, or select Delete rule and confirm with OK.
- In classic Outlook, reopen View Settings > Conditional Formatting and clear the checkbox beside the rule to disable it temporarily.
- In classic Outlook, select the rule and choose Condition or Font to revise it, or Delete to remove it.
Microsoft also warns that new Outlook does not include every conditional-formatting option available in classic Outlook. A missing option can therefore reflect a client difference. Avoid trying to reproduce a classic-only rule by choosing a superficially similar condition that matches different messages.
Make Cc coloring a reading aid, not a priority policy
Use this rule if identifying copied correspondence would make your inbox easier to scan. Keep the interpretation narrow: Cc is a recipient field, and its presence does not reliably determine urgency, ownership, or whether a response is needed.
The most useful setup is one you can understand at a glance and undo without disturbing your other formatting.
- Use View > View Settings in classic Outlook, or Settings > Mail in new Outlook and the web interface.
- Select the condition for your address appearing in Cc, rather than searching for the text
CC. - Choose a readable color that has a distinct meaning alongside your existing formatting.
- In new Outlook and the web interface, check competing rules because the higher rule takes precedence.
- Confirm the result against a known copied message, and disable the rule temporarily if you want to compare the original appearance.
Cc highlighting is a small customization with a concrete payoff: Outlook can show a useful piece of recipient information directly in the message list. Once the correct condition and color are in place, you can scan copied correspondence more easily while still deciding what deserves attention from the message itself.
