Outlook is changing text format to justified with hyphenated words

I have created an email campaign and sent a "test" email to myself. When I open the email campaign, the text format is suddenly changed to "justified" causing some words to be hyphenated where they shouldn't be. The bulleted paragraphs are also misaligned. I am only seeing this text format issue in Outlook but not Gmail or Yahoo as I've also sent test emails to those two and they look fine. Is this only an issue for Outlook users? Is anyone else having this issue?
