What is the keyboard shortcut for strikethrough in Outlook and why it matters
The keyboard shortcut for strikethrough in Outlook helps you mark edits directly in the email body, signal deletion, or indicate updates without removing content. In Outlook’s editor (which borrows its formatting toolkit from Word), strikethrough is a toggle that can be activated or deactivated with a keyboard combination. Knowing the correct keystroke on your platform saves you from navigating menus and preserves your typing momentum. Shortcuts Lib highlights these basics because consistent shortcuts reduce cognitive load and make revision faster across devices. The keyword priority is to keep your message concise while retaining the exact form of the original text.
On Windows, the traditional approach uses Ctrl+5 to toggle the effect. On macOS, the common equivalent is Cmd+Shift+X. The web version (Outlook on the web) often follows browser/editor conventions and may support the same combination, but variations exist depending on updates and browser configuration. If you ever see the Strikethrough button in the Format toolbar, you can also apply or remove the style by selecting text and clicking that button. This section demonstrates practical, platform-specific shortcuts and explains how to adapt them to your workflow.
