I'm trying to send HTML email from my PC running Windows 10 and Outlook 2016. Whether I create the email in Outlook (doing simple things like creating hyperlinks and bold or italicized text) or from one of the HTML email templates in Dreamweaver, the email I send arrives without most of the formatting intact. For example, the hyperlinked text arrives with the text and the web address separate, instead of having the text highlighted and the web address invisible. For email with images, the images are gone with only a reference, and tables are missing. I can send the same email from my Mac with Outlook version 15.26, and the email arrives just fine.

What's going on. A few days ago, I was able to send HTML email from my PC just fine, and I don't think anything has changed. I get my updates automatically. Did an unannounced update break something?

Thanks for the help.
