How do you convert Apple Mail with an attachment to a PDF and still have access to the attachment?

Hello toms37328193

Sorry for the delay in response to your query and apologize for the inconvenience caused. As per the description above, you want to convert an email with an attachment  into a PDF file, Is that correct?

You can convert an email into a PDF file but the attachment within the Email will not get converted with the email in PDF file, to convert the attachment as well you have to save it separately and then can convert it to a PDF file.

You may refer to PDF creator, create PDF files | Adobe Acrobat DC

Hope this helps and let us know how it goes.

Regards,

Anand Sri.
