This is strange behaviour, @steve1955, but it might be because of how you are making the email body.
I can't be sure, though ... so you may wish to edit your original question above (tap the dots to edit) and embed an image so that it is visible in the browser and not attached as a file.
This will help folks get a bit more context as to how your flow works in order to assist you and will help others in need identify this as their problem. 👍

You may just need to tap the 'Code view' button in the Outlook Send an email V2 action to insert the column data. It looks something like this:
</>
Then it will insert the HTML from the formatted column correctly.
I can't remember if there are differences, though between the 'Rich text' multiple line column type and the 'Enhanced rich text (Rich text with pictures, tables, and hyperlinks)' multiple line column type.

You can also use the Send an HTTP request to SharePoint to get the item and when you make the call to the list item make sure that you:
- Use the Select query to include FieldValuesAsHtml
- Use the Expand query to include FieldValuesAsHtml
This will then allow you to select the HTML of the field in full if it is available.
This will require a bit more knowledge, though to nail perfectly.

Again, though, it all depends on what your actual setup is ... so we might know more if you edit your original question with imagery.
I say to edit the original question specifically and not to reply with it because often folks won't even scroll down here without it.
