How to remove attachment from email download.

Please be more specific about your issue and what were you trying to do.

Are you asking how to edit an email document that was exported to a PDF using Adobe Acrobat Pro ?

As far as I am aware of,  Adobe Acrobat Pro is a PDF viewer/reader and a PDF editor, not a web browser nor an Email Client program with anti-spamming filters.

As such, it is not a software that was designed to handle how emails are sent or received among computer/Internet users

(with or without attachments).

It is confusing trying to understand your question since there is no additional information  that would help describe your exact issue.

Does this question relates to Adobe Acrobat Pro at all ? ( which is the support community forum where you've posted this inquiry)
