This question is specific to the "New Outlook" for Windows that you can enable in preview form, not the regular version.
With the regular version of Outlook for Windows, we frequently use the "Insert as Text" option which lets you select an HTML file and have that HTML render in the email body. We are looking for a way to achieve the same thing in the new Outlook, but I can't find the option.
Is there any way to do this in the new Outlook? I see that I'm able to open the HTML file in a web browser, select all, copy, and paste into an email message, but the formatting is not perfect. I'm looking for a method that is more like the old way, where you select the HTML file.
