Part 1.3. How To Do Double Strikethrough on Outlook

Double strikethrough uses two lines rather than just one. You can use it when you strongly oppose an idea or when the information is very incorrect or not relevant. You can also use this to just make the strikethrough more noticeable, especially if the recipient has poor vision.

To use double strikethrough on Outlook:

  1. Start composing a new email.
  2. Highlight the text to strikethrough.
  3. Right-click on the selected text. Click Font.

Part 1.4. How To Remove Strikethrough on Outlook

Oops! Did you apply strikethrough to the wrong word, phrase, or sentence? Do not worry. It is reversible. The easy way out is to use the Undo feature (CTRL + Z) if you just added the strikethrough. But what if adding it was not the last thing you did? Using Undo repeatedly can work, but it will also remove all the progress you made after adding the strikethrough. You would not want that. Follow this set of instructions instead:

  1. Select the text in the Outlook email that has a strikethrough.
selecting the text with strikethrough
  1. Click Format Text.
  2. Click Strikethrough. This should remove the strikethrough.

You can also follow the other methods you use to add a strikethrough in Outlook. They all work to reverse the action.

Part 2. How to Strikethrough in Outlook Web App

The Outlook desktop app will only work if your account is activated. Do not worry if it's not. You can use the web app instead. It offers almost all the features offered by the desktop app. That said, you can apply strikethrough to text on the Outlook web app. Here's how to do that:

  1. Launch your preferred web browser.
  2. Go to Outlook's website and log into your account.

Part 3. Tips and Scenarios for Applying Strikethrough in Outlook Email

You have learned how to add strikethrough in Outlook, as well as how to remove it. But when should you use this text-formatting style? Here are some scenarios.

  • Indicate that information is no longer accurate.

Suppose you want to inform the recipient that some information is no longer accurate. Perhaps new knowledge has debunked it. You can write that information, then cross it out using a strikethrough. Next to it, write the updated information. The recipient will easily understand what it means.

It's faster to use strikethrough than writing a whole transition sentence that indicates some changes have occurred. Furthermore, it is easier to read. Thus, both you and the recipient benefit from this simple writing technique.

  • To highlight parts that have been changed or need to be changed

In negotiations, you will often need to edit sentences and clauses until both parties agree. You can use strikethrough for this; it is universally understood. Copy the text, strikethrough the text that needs to be changed. Add the suggested changes after that sentence. Besides negotiations, you can also use a strikethrough for corrections.

  • Show rejected suggestions or discarded ideas.

Maybe you are writing a report or minutes of the meeting. It is mandatory to add what has been agreed upon during the session. Furthermore, it is wise to also include the rejected or scrapped ideas. And how do you separate them? Simple. You just need to add a strikethrough to the discarded ones.

Part 4. How to Strikethrough Text in Email Attachment

Strikethrough is most commonly used in negotiations. As stated above, Outlook allows you to add strikethrough to text. However, most of the time, the text that needs changing is in a file. For example, you are not copy-pasting text from a contract to an email. Instead, you will attach the contract - often a PDF - to the email. That said, you must add the strikethrough in the PDF.

What tool allows you to do that? There are plenty, but the best one is Wondershare PDFelement. It is available on Mac, Windows, iOS, and Android. The best thing is you can also send the PDF through Outlook without leaving Wondershare PDFelement.

People Also Ask

    Here are some FAQs regarding strikethrough in Outlook.

  • 1. Will the recipient see the strikethrough if they're using a different email client?
    Most email clients support text formatting. Thus, most of the time, your recipient will see the strikethrough. It will only not appear if they are viewing the email as plain text. If they are on mobile and are using an outdated app, the strikethrough may also not appear on their end.
  • 2. Is it professional to use strikethrough in business emails?
    In companies with a relaxed culture, it is completely okay to use strikethrough. However, in others, excessive use of strikethrough in email would be considered unprofessional. Therefore, we recommend getting a feel to determine whether or not it is okay. If you are unsure about how the recipient will interpret the strikethrough, we recommend not using it.
  • 3. Are there any alternatives to strikethrough for indicating changes in emails?
    The best method is to use strikethrough in Outlook 365. It immediately conveys that what you formatted has been changed. Less effective methods include highlighting the text, using bold or italicized formatting, using a striking font color, or a combination of these.
