Description

Description

I would like to be able to compose mails with an HTML body, as you can do on iOS or for example using an Outlook interop MailItem (on Windows).

MAUI gives you only an Exception on Windows (EmailImplementation):

if (message != null && message.BodyFormat != EmailBodyFormat.PlainText)
				throw new FeatureNotSupportedException("Windows can only compose plain text email messages.");

Public API Changes

(none to my knowledge)

Intended Use-Case

Format the body of a mail e.g. for better readability or corporate identity stuff.

Research direction
Start by examining the existing Email.uwp.cs file at the linked path to understand the current implementation. Research Windows APIs for composing HTML emails, such as Windows.ApplicationModel.Email.EmailManager or using the Windows Mail app. Look at the iOS Email implementation in the repository for reference on how HTML bodies are handled on other platforms. Implement a solution that replaces the current exception with code that launches the email compose dialog with an HTML body.
