Alexey Bezrodny / Getty Images How to Wrap Long Lines Automatically in Outlook When you wrap long lines of text, the Outlook email client automatically breaks sentences away from the current line to start on a new line. This shortens the length of all outgoing emails and is similar to narrowing the margins of the writing space. Open Outlook and go to the File menu. Select Options. In Outlook Options, select Mail. Scroll to Message format. In Automatically wrap text at character, enter a number to indicate where you want Outlook to wrap text. Keep it between 65 and 70 characters. Select OK to apply the changes and close the window. You may have to experiment with the number of characters to get your emails looking the way you want. If you need to change the number of characters, repeat the steps until you are satisfied. Was this page helpful? Thanks for letting us know!
