Long lines can be difficult to read in emails, so it’s always good email etiquette to break up the lines of your messages to somewhere between 65 and 70 characters. Microsoft Outlook has a handy setting that lets you set line breaks to the number of characters you want. Here’s how to adjust the number of characters at which a line break occurs in Outlook.

When you wrap long lines of text, the Outlook email client automatically breaks sentences from the current line to start a new line. This shortens the length of all outgoing emails and is similar to reducing the margins of the writing space.

Open Outlook and go to the File menu.

Select Mail in Outlook Options.
