When you add a URL to an email message in Outlook.com or Outlook on the web, or when you receive an email message with a URL in the body, you'll see a rich preview that includes a link title, thumbnail image, and description of the link. This is called a link preview.
With the Link Preview feature turned off, a URL looks like this: https://www.microsoft.com.
With the Link Preview feature turned on, the same URL looks like this:
Note: Link Preview is turned on by default. If you don't see a link with a thumbnail image, title, and description like the one shown above and want to see them, turn Link Preview on.
Add a link preview in an email message
-
When composing an email message, type a URL in the message body. For example, you could type https://microsoft.com.
-
If Link Preview is turned on, it automatically provides the site's name, description, and thumbnail image (if available) in the message body.
Note: To open or follow a link preview, simply click it like any other hyperlink.
Turn off the Link Preview feature
Link Preview is turned on by default in Outlook.com and Outlook on the web, so you see rich previews of URLs when you're reading and composing email messages. However, you can turn off Link Preview if you prefer.
