How To Change Flag Color In Outlook : Assigning Custom Flag Colors

by

Resizing the folder pane font in Outlook 365 improves readability for your navigation sidebar. But what if you want to change the color of a flag instead? Many users need to know how to change flag color in outlook to better organize their emails. Flags help you mark important messages, and different colors can mean different priorities. This guide walks you through every method, from simple clicks to advanced rules.

Flags in Outlook are not just for reminders. They are visual markers that sit next to your messages. By default, flags are red, but you can change them to other colors. The process is not always obvious, so we break it down step by step. Whether you use Outlook 365, 2021, or the web version, you will find a solution here.

How To Change Flag Color In Outlook

Changing a flag color in Outlook is easier than you think. You can do it for individual emails or set up automatic rules. The method depends on your Outlook version and whether you want a permanent change. Let’s start with the basic steps.

Change Flag Color For A Single Email

To change the flag color for one message, follow these steps:

  1. Open Outlook and go to your inbox.
  2. Right-click the flag icon next to the email you want to change.
  3. From the menu, select “Set Quick Flag” and then choose a color.
  4. You will see options like Red, Blue, Green, Orange, Purple, and Yellow.
  5. Click your desired color. The flag changes instantly.

That’s it. The color now appears next to the email in your list. This works for both read and unread messages. If you want to remove the flag, right-click and select “Clear Flag.”

Using The Follow-Up Menu

Another way is through the Follow-Up menu. This method gives you more options, like setting a due date.

  1. Select the email you want to flag.
  2. Go to the “Home” tab in the ribbon.
  3. Click the “Follow Up” button in the Tags group.
  4. A dropdown menu appears. Hover over “Set Quick Flag” to see colors.
  5. Pick a color. The flag updates immediately.

You can also use this menu to add a reminder. This is helpful for tasks that need a deadline. The color stays until you clear it manually.

Change Flag Color In Outlook Web

Outlook on the web (OWA) works slightly different. The flag options are more limited, but you can still change colors.

  1. Log in to Outlook.com or your Office 365 web account.
  2. Find the email you want to flag.
  3. Hover over the message. A flag icon appears on the right.
  4. Click the flag. It turns red by default.
  5. To change color, right-click the flag icon (or use the three-dot menu).
  6. Select “Set Flag” and then choose a color from the list.

Note that web version only supports a few colors. You cannot create custom colors here. For more control, use the desktop app.

Advanced Flag Color Settings

If you need more than basic colors, Outlook has advanced options. You can create rules that automatically flag emails with specific colors. This saves time and keeps your inbox organized.

Create A Rule To Auto-Color Flags

Rules let you assign flag colors based on sender, subject, or keywords. Here is how to set one up:

  1. Go to the “File” tab and select “Manage Rules & Alerts.”
  2. Click “New Rule” and choose “Apply rule on messages I receive.”
  3. Select a condition, like “from people or public group.”
  4. Click “Next” and then “Yes” to confirm.
  5. In the action list, check “flag message for follow up.”
  6. At the bottom, click the blue “flag message” link.
  7. A dialog box opens. Choose a flag color from the dropdown.
  8. Set a due date if needed. Click OK.
  9. Finish the rule and name it. Click “Finish.”

Now, any email that matches the condition gets flagged with your chosen color. This works great for important contacts or project emails.

Using Categories Instead Of Flags

Categories are another way to color-code emails. They are not exactly flags, but they serve a similar purpose. Categories appear as colored bars next to messages.

  1. Select an email.
  2. Go to the “Home” tab and click “Categorize.”
  3. Choose a category color, like Red, Blue, or Green.
  4. You can rename categories by clicking “All Categories.”

Categories and flags can work together. Use flags for urgency and categories for topic. This gives you a dual-color system.

Troubleshooting Flag Color Issues

Sometimes flag colors do not change as expected. Here are common problems and fixes.

Flag Color Not Updating

If the color stays red after you change it, try these steps:

  • Refresh your inbox by pressing F5.
  • Close and reopen Outlook.
  • Check if the email is in a shared mailbox. Some shared folders restrict flag changes.
  • Make sure you are not using a read-only view.

Missing Flag Colors

If you see only red flags, your Outlook version might be old. Update to the latest version. Also, check if your account is connected to Exchange. Exchange supports more flag features than POP or IMAP.

Flag Colors Reset After Sync

This happens often with mobile devices. When you change a flag color on your phone, it may not sync back to Outlook. To fix this, change the color directly in Outlook desktop. Then sync manually.

Customizing Flag Colors With VBA

For power users, VBA (Visual Basic for Applications) can change flag colors programmatically. This is advanced and requires coding knowledge.

Sample VBA Code

Here is a simple script to change a selected email’s flag color to green:

Sub ChangeFlagColor()
    Dim objMail As Outlook.MailItem
    Set objMail = Application.ActiveExplorer.Selection.Item(1)
    objMail.FlagStatus = olFlagComplete
    objMail.FlagColor = olGreen
    objMail.Save
End Sub

To use this, press Alt+F11 to open the VBA editor. Insert a new module and paste the code. Run it while an email is selected. This gives you full control over flag colors.

Flag Colors And Their Meanings

Assigning meaning to colors helps your workflow. Here is a suggested system:

  • Red: Urgent, must act today.
  • Blue: Follow up this week.
  • Green: Low priority, read later.
  • Orange: Personal emails.
  • Purple: Project-related.
  • Yellow: Waiting for reply.

You can adapt this to your needs. Consistency is key. Share the system with your team for better collaboration.

Keyboard Shortcuts For Flags

Speed up your workflow with shortcuts. Here are the most useful ones:

  • Ctrl+Shift+G: Open the Follow Up dialog.
  • Insert: Toggle flag on selected email (default red).
  • Ctrl+Shift+1: Set red flag (if custom shortcuts are set).

You can create custom shortcuts in Outlook options. Go to File > Options > Customize Ribbon > Keyboard Shortcuts.

Flag Colors In Shared Mailboxes

If you use a shared mailbox, flag colors may behave differently. Changes you make might not show for others. This is because flags are personal, not shared. Each user sees their own flags.

To make flags visible to the team, use categories instead. Categories can be shared if you set them up in Exchange.

Using Flags With Tasks

Flags are not just for emails. You can flag tasks and calendar items too. The process is similar:

  1. Open a task or appointment.
  2. Click the “Follow Up” button in the ribbon.
  3. Choose a flag color.
  4. The item appears in your To-Do bar with that color.

This helps you see all flagged items in one place, regardless of type.

Resetting Flag Colors To Default

If you want to go back to red flags, reset the settings. Here is how:

  1. Right-click any flagged email.
  2. Select “Set Quick Flag” and then “Red.”
  3. For rules, go to Manage Rules & Alerts and delete or edit the rule.

This restores the default behavior. Note that clearing all flags does not change the color system.

Flag Colors In Outlook For Mac

Outlook for Mac has similar flag options. To change a flag color:

  1. Right-click the email and select “Flag.”
  2. Choose a color from the submenu.
  3. Or use the toolbar button and pick a color.

Mac version supports the same colors as Windows. However, rules for auto-flagging are more limited.

Third-Party Add-Ins For Flags

If you need more flag features, consider add-ins. Tools like “Flagify” or “Color Flag” add extra colors and automation. Install them from the Office Store. Be cautious with permissions.

Common Mistakes When Changing Flag Colors

Users often make these errors:

  • Clicking the flag icon instead of right-clicking. Left-click toggles the default red flag.
  • Expecting flag colors to sync with mobile apps. Some mobile clients do not support custom colors.
  • Using flags for permanent categorization. Flags are meant for follow-up, not long-term labels.

Avoid these to keep your system working smoothly.

Best Practices For Flag Color Usage

To get the most out of flag colors, follow these tips:

  • Limit yourself to 3-4 colors to avoid confusion.
  • Use the same color for the same purpose every time.
  • Clear flags after completing the task.
  • Combine flags with categories for deeper organization.

This keeps your inbox clean and your workflow efficient.

Frequently Asked Questions

Can I change the default flag color in Outlook?

No, Outlook does not have a setting to change the default red flag. You must manually change each flag or use a rule.

How do I remove a flag color from an email?

Right-click the flag icon and select “Clear Flag.” This removes the color and the follow-up marker.
