NEW Outlook Email Format is messing up

I am having major issues in NEW Outlook with the formatting of my emails. I will compose an email, format it properly, and send it. The receiver gets an email with weird large spacing, no spaces where needed, and bullet alignments all messed up. It does not look that way when I send it why are the emails messed up when received? I am using HTML text which has all the issues. I have tried plain text but it does not allow formatting I need like bullets etc. I need this fixed as I can not go back to desktop Outlook as it freezes and crashes all the time. HELP PLEASE!
