Whether you choose to label them "Clients," "Family," "Bills," or any number of other choices, they simplify your Inbox and help you organize your mail. If you want to add subfolders—say one for each member of your family—inside a folder, you can do that too. Outlook also provides categories you can assign to individual emails. Use custom email folders, subfolders and categories to organize your Outlook Mail account.

  3. Press the Enter key on your keyboard.

  3. A text box appears beneath the folder you right-clicked on. Type the name you want to give the new folder.
  4. Press the Enter key.

    1. Note: The same steps work for creating deeper subfolders under any new subfolders. Simply repeat steps 1-4 for each subfolder you want to create.

You can also click and drag a folder in the list and drop it on top of a different folder to make it a subfolder.

After you've created several new folders, you can click on an email and use the Move to option at the top of the Mail screen to move the message to one of the new folders.

  2. Click Create new subfolder.
  3. Enter a name for the folder.
  4. Press Enter.

Click and drag individual messages from your Inbox (or any other folder) to the new folders you make to organize your email.

You can also set up rules in Outlook to filter emails from specific senders to a folder so you don't have to do it manually.

Use Categories to Color Code Your Messages

You can use the default color codes or personalize them by setting up your category preferences. To do this in, you go to the Settings Gear > View Full Settings > General > Categories. There, you can select the colors and categories and indicate whether you want them to appear at the bottom of the folder pane, where you click to apply them to individual emails. You can also access the available categories from the More icon.

To apply a category color to an email using the More icon:

  1. Open the email in the message list.
  2. Select the Categories drop-down menu at the top of the message.
  3. Choose the category you want to apply to the email. A color indicator appears next to the email in the message list and the header of the opened email.


  1. In your message list, right-click the email you want to categorize.
  2. Select Categorize in the menu that appears.
  3. Choose the category you want to apply to the email. A color indicator appears next to the mail in the message list and the header of the opened email.

The process is similar in Outlook. Locate the Categories icon in the ribbon and place a check in the box next to colors you want to use or rename. Then, click individual emails and apply the color code. You can apply more than one color code to each email if you are a particularly organized individual.
