Saving an Outlook email as a PDF is a process of converting an email message from Microsoft Outlook into a Portable Document Format (PDF) file. This allows the email and its attachments to be viewed, printed, and shared independently of the Outlook application. For example, it is useful for archiving important emails, sending them to non-Outlook users, or creating backups.
Saving Outlook emails as PDFs has become increasingly important due to the widespread use of PDF as a standard document format. PDFs are portable, secure, and easy to view on various devices. The ability to save Outlook emails as PDFs has been a part of the application since its early versions and has been continuously improved over time.
