How to Save an Outlook Email as PDF (With Its Attachments)

Some emails are too important to trust to an inbox. Approval chains, negotiated terms, that message where the client finally wrote 'confirmed' in plain text: these deserve to exist as files, outside any mail server, retention policy, or accidental archive-folder purge. The standard way to freeze an Outlook email is the print-to-PDF path, and it is worth saying plainly: this capability belongs to Outlook and your operating system, not to any third-party tool. Where a toolkit like PdfWill earns its place is immediately afterwards, when that raw export needs to become a proper archive document.

The export itself takes seconds. In Outlook for Windows, open the email and choose File, then Print, and select 'Microsoft Print to PDF' as the printer. On a Mac, use the Print dialog and pick 'Save as PDF' from the PDF dropdown. Outlook on the web works the same way through the browser print dialog. The output captures the sender, recipients, timestamp, and body, which is exactly the metadata that makes the record defensible later. Tip: expand any collapsed quoted text first, or your PDF will preserve the collapse for eternity.

Here is the catch nobody mentions: printing an email does not print its attachments. That signed proposal PDF and the two spreadsheet exhibits are separate files, and a printed email that says 'see attached' with nothing attached is an archive with a hole in it. Save each attachment to disk the normal way. If an attachment is a Word or Excel file, export it to PDF too, using Word to PDF or Excel to PDF, so every exhibit speaks the same format. Now you have one email PDF plus a small pile of attachment PDFs.

This is where merge turns a pile into a record. Drop the email PDF in first, then the attachments in a sensible order, and download a single bound file: the message and its exhibits, stapled together the way a case file would be. Because PdfWill processes everything locally in your browser with zero uploads, a confidential negotiation thread never touches an external server. If the result runs heavy, perhaps those exhibits were scanned, the compress tool slims it down while keeping the text selectable, which your future search-happy self will appreciate.

Two finishing moves for serious archives. If any attachment was a scan, meaning pictures of text rather than text, run it through OCR to get a searchable PDF; an archive you cannot search is just a well-organized haystack. And adopt a naming discipline now, not later: something like 2026-06-07_client_approval.pdf sorts itself chronologically forever. The whole routine, print, save, convert, merge, compress, takes under five minutes per email thread. Compare that with the hour you will spend hunting through a departed colleague's mailbox, and the math is not close.
