After reviewing the behavior of the “Remove Format” button in the Dynamics 365 rich text editor, we have confirmed that its current design removes only inline-level formatting (such as "span", bold/italic, and inline font-size or font-family), while styles applied directly to block-level elements like "p" tags are not removed.

As a result, when font-family or related styles remain on "p" tags and the email is opened in Outlook, Outlook evaluates fonts on a paragraph-by-paragraph basis. This can cause inconsistent font rendering between paragraphs, even when the content is the same language (for example, Japanese).

While this behavior is understood to be by design, from a user perspective it can be confusing, as using “Remove Format” does not fully normalize the visual appearance.

It would be very helpful to have:

・An option to fully remove font-related information inside "p" tags when “Remove Format” is applied

This would help prevent font inconsistencies when composing emails.
