Similarly, we can also add these properties for the new composing, replying, or forwarding email too. Here, this tutorial will guide you to add these properties for editing emails easily in Outlook.

When composing/replying/forwarding an email in the message window, we can add the follow up flags, custom flags, or reminder to the email easily.

1.1.1 Add follow up flag to a single email before sending

In the new composing, replying, or forwarding message window, click Message > Follow Up, and then pick up a flag from the drop-down menu as you need.

(1) Type in the flagged text in the Flag To box;
