Outlook includes an accessibility tool called “Read Aloud” that will read an email to you. This is useful for people with vision problems, but also if you prefer to hear a long passage rather than read it. You can even use it to understand how words are pronounced if you’re not sure, making it an ideal tool if you’re working in a non-native language. Here’s how to use it, and how to hide it if you don’t need it.
The Read Aloud tool is, by design, simple to use. Select the message you want to read and then click Home > Read Aloud.
If you’ve opened the message in a separate window, click Message > Read Aloud instead.
Whichever route you use, when you click “Read Aloud” the narrator will start reading the body of the message and Outlook will display the Read Aloud controls.
You can use these controls to decide what the narrator reads and how they read it. The rewind and forward buttons cause the narrator to go back or forward a line. Because Outlook determines the start and end of a line by where the line breaks are (which generally means where the author of the message hit Return), the rewind and forward buttons usually move the narrator back or forward one paragraph. You can use the pause button to pause the narration and the play button that appears in its place to resume the narration.
