iPhones' iOS' Mail app e-mail questions...

Hello,

A couple questions in iOS v17.1.1's preinstalled Mail app in iPhones:

1. How do I forward an original e-mail, with everything, without composing a new e-mail? I need to forward spam e-mails with everything including their headers. From what I read online, it is not possible. Is this correct? :(

2. How come some e-mails are not AirPrintable? This is noticeable with Office 365 e-mail account. No problems printing from the outlook.com web site.

Thank you for reading and hopefully answering soon. :)
