How to Strikethrough Text in Microsoft Outlook: A Step-by-Step Guide

Strikethrough text in Microsoft Outlook is a way to cross out text in an email, giving the impression that the text is no longer valid or has been completed. To do this, simply highlight the text you want to strikethrough, go to the “Format Text” tab, select the “Strikethrough” button (which looks like a “T” with a line through it), and voila! Your text will now appear with a line through it.

After you complete the action of adding a strikethrough to text in Outlook, the text will remain edited in this way until you choose to remove the strikethrough. This visual cue can be helpful for indicating that something has been removed from consideration, completed, or is otherwise not applicable in the context of your email.


When it comes to drafting emails, Microsoft Outlook is one of the most widely used platforms, both in the professional world and for personal use. With its array of features and tools, Outlook allows users to customize their messages in a plethora of ways to fit their needs. One such feature is the ability to strikethrough text. But why is this feature important, and who stands to benefit from using it?

Think about it: How often have you sent or received an email that contained an error or outdated information? Or perhaps you’ve been part of an email chain where tasks were listed and needed to be marked off as they were completed. In these contexts, the ability to strikethrough text is incredibly useful. Not only does it allow for clear communication without the need to delete text, but it also maintains the integrity of the original email for future reference. Whether you’re a project manager keeping track of tasks, an editor noting changes that need to be made, or simply someone who wants to ensure their email communications are as clear as possible, knowing how to strikethrough text in Outlook is an essential skill.

Step by Step Tutorial: Strikethrough Text in Microsoft Outlook

Before diving into the steps, it’s important to understand that by following these instructions, you’ll be able to visually communicate to your recipients that certain pieces of text have been crossed out for a reason, without actually removing the text from the email.

Step 1: Open the email

Open the email you want to edit in Microsoft Outlook.

This is self-explanatory – you can’t strikethrough text if you don’t have the email open!

Step 2: Highlight the text

Highlight the text you wish to strikethrough by clicking and dragging over it.

Make sure you only highlight the text you want to mark. If you highlight too much, you might strikethrough text you didn’t mean to!

Step 3: Access the “Format Text” tab

Navigate to the “Format Text” tab at the top of your Outlook window.

This is where all your text formatting tools are located, including the strikethrough option.

Step 4: Click the “Strikethrough” button

In the “Font” group, click on the “Strikethrough” button.

It’s the button that looks like a “T” with a line through it. Once you click it, your highlighted text will automatically be struck through.
