The fastest way to convert an Outlook or Office 365 email to PDF depends on what you actually need. For a single email, the built-in Print to PDF works. To keep attachments, merge several emails into one file, or process a whole folder, you need a real converter — because Print to PDF drops attachments and can't combine messages.
This guide compares seven methods, with and without extra software, so you can pick the right one in a minute.
Key Takeaways
Outlook's built-in Print to PDF handles one email at a time but discards attachments and can't merge or batch.
The "new Outlook" for Windows removed the old "Save as PDF" option — Microsoft confirms Print to PDF is now the only built-in route (Microsoft Support).
To keep attachments, merge multiple emails, or convert PST/OST/MBOX/OLM archives, upload the raw .eml/.msg files to PDFen — no Outlook required.
You can also forward an email straight to PDFen and get the PDF back, use the API, or convert through ChatGPT or Claude with the PDFen connector.
Records matter: the FBI logged $2.77 billion in business email compromise losses in 2024 alone (IC3), and FINRA Rule 4511 requires firms to keep email for at least six years.
Most people land here for one of three reasons: a quick single email, a batch with attachments, or hands-off automation. Here are the three methods that cover the vast majority of cases, with honest trade-offs.
Method | Best for | Pros | Cons |
Built-in Print to PDF (no software) | One simple email, no attachments | Free; already installed; instant | No attachments; can't merge; no batch; broken/limited in new Outlook |
Upload to PDFen ( | Attachments, merging, bulk, archives | Keeps attachments; merges; handles PST/OST/MBOX/OLM; PDF/A; no install | You first export the email out of Outlook |
Forward to PDFen | Fastest one-off, any device | Zero install; works from phone; converts attachments | Needs a free account to set up your address |
Getting an email out of your inbox and into a clean PDF takes seconds — once you pick the right method.
The rest of this guide walks through all seven methods, then explains what happens to attachments and forwarded ("wrapper") emails, and ends with a full comparison and FAQ.
Outlook's built-in Print to PDF is the no-cost baseline: it turns the email you're viewing into a PDF using a virtual printer. It works everywhere, but it only captures the on-screen message — attachments are not included, and there's no way to merge or batch.
The exact steps differ per environment, and Microsoft changed them recently:
Classic Outlook (Windows): File → Print, choose Microsoft Print to PDF as the printer, click Print, then pick a filename. (Microsoft Support)
New Outlook (Windows): open the message, then More actions (⋯) → Print → Print, and select Microsoft Print to PDF. There is no native "Save as PDF" type anymore.
Outlook on the web / Office 365: open the email, More actions (⋯) → Print, then set the browser's destination to Save as PDF.
Outlook for Mac: File → Print (or ⌘P), then use the PDF dropdown → Save as PDF in the print sheet.
If you recently switched and thought you were losing your mind, you're not. Microsoft's own support page states plainly that "New Outlook doesn't include PDF as one of the defaults Save as types." The redesign removed the familiar export, leaving only the Print to PDF workaround — and that workaround drops attachments. Threads on Microsoft's community are full of it: "In the old version of Outlook, you could easily save an email in PDF format. How do you do that in the New Outlook?" (Microsoft Q&A).
So Print to PDF is fine for a single, attachment-free email you just need to file. For anything beyond that, keep reading.
Adobe Acrobat installs an Acrobat ribbon tab inside classic Outlook for Windows. It's far more capable than Print to PDF: you can convert selected messages or whole folders, merge them into one PDF, and include attachments when you enable that setting (Adobe Experience League).
The catch is twofold. First, it's subscription-based and desktop-focused — see Adobe's pricing. Second, the ribbon is tied to classic Outlook; it does not restore folder or merge conversion inside the new Outlook or on the web. If you've already moved to new Outlook, an Acrobat subscription alone won't bring batch conversion back unless you switch back to classic.
Adobe Acrobat's Outlook integration can merge selected emails and folders into a single PDF and include attachments, but it requires a paid subscription and runs only inside classic Outlook for Windows (Adobe). It offers no option for users on the web or new Outlook.
Uploading the raw email file to PDFen's email-to-PDF tool is the most reliable way to convert with attachments intact — and it runs in your browser, with no Outlook or desktop app required. PDFen reads the original .eml or .msg, renders the message body, and converts each attachment too.
First, get the email out of Outlook:
Classic Outlook: drag the email onto your desktop, or File → Save As and choose the .msg format.
New Outlook / web: open the message, then More actions (⋯) → Save as (or drag it out) to get an .eml file.
Mac: drag the email from the message list to a Finder folder to create an .eml.
Then drop the file(s) onto pdfen.com/email-to-pdf and convert. Because PDFen reads the file rather than a screenshot, it preserves the headers (From, To, Subject, Date, Message-ID) and can output PDF/A for long-term, compliant archiving — PDF/A has been the ISO standard for digital preservation since ISO 19005-1:2005. For the forensic side of this — header preservation and SPF/DKIM/DMARC results — see our guide on converting email to PDF with headers.
Have hundreds of emails? Upload an entire Outlook PST or OST archive, a Mac OLM, an MBOX file, or a ZIP of .eml/.msg files. PDFen extracts the messages, shows them in a preview so you can pick and reorder, and converts them in one run. This is the answer to the most common complaint on Microsoft's forums — "we have hundreds of emails to upload to client files… we are unable to print multiple emails to a PDF" (Microsoft Q&A). For more on these formats, see email archive file formats explained.
One archive upload converts an entire mailbox — no opening and printing emails one by one.
To combine several emails into a single, page-numbered PDF, use PDFen's merge-email-to-PDF tool. Upload the .eml/.msg files (or an archive), arrange them in the order you want, and PDFen stitches them into one continuous document instead of dozens of separate files.
This is the use case native Outlook simply doesn't cover. There's no "combine selected emails into one PDF" button anywhere in classic, new, web, or Mac Outlook — each message prints separately. Merging matters most for legal bundles, client files, and complete conversation threads that need to read as one record. A 2026 forum post captures the pain exactly: an attorney's client "needs all of my email communications… I've exported into pst but honestly I'm struggling" (Microsoft Q&A).
The quickest one-off method needs no upload at all: forward the email to your personal PDFen address and get the PDF back. After you create a free account, PDFen gives you addresses like convert+123456789012@inbound.pdfen.com (and a merge+… variant). Forward any email to it from Outlook — even from your phone — and PDFen converts it automatically.
This works from any device and any mail client, which makes it ideal when you're away from your desk. It also handles something Print to PDF can't: the original email's attachments come along for the ride.
Forwarding an email to a dedicated address turns conversion into a zero-install, send-and-forget step that works from any device. PDFen detects the forwarded ("wrapper") message, converts the original email it contains, and processes its attachments — no software, no upload screen, no Outlook version dependency.
For people who live in Outlook, an add-in is the smoothest path: convert the email you're reading to PDF in place, without exporting or uploading anything. The PDFen Outlook add-in reads the open message (including its attachments) and returns a PDF in a side panel.
It works inside Outlook on the web and new Outlook, so it sidesteps the "new Outlook removed Save as PDF" problem entirely. Sign in once, open any email, and convert.
If you convert email to PDF regularly — archiving a shared mailbox, attaching emails to case files, feeding a records system — automate it with the PDFen API. Post an .eml or .msg to the convert/email endpoint, poll for completion, and download the finished PDF. Create a token under your API tokens page and you can wire conversion into any script, scheduler, or backend.
The API is also what powers the next method, where an AI assistant does the work for you.
Here's a method no one else covers: hand the job to an AI assistant. There's an honest distinction to make, though — what works with PDFen connected, and what doesn't without it.
Without a tool connected, a chatbot can't truly convert your email. You can paste the text and ask for a summary, but ChatGPT or Claude has no rendering engine and no access to your mailbox, so it can't produce a faithful PDF with the real layout, headers, and attachments. At best you get the browser's own "print to PDF" of the chat — not the email.
With the PDFen connector (MCP), the assistant gains real tools. Connect PDFen's MCP server (https://pdfen.com/mcp/sse) with your API token, and Claude or ChatGPT can call start_conversion, then hand you a download link to a genuine PDF. You stay in the chat; PDFen does the conversion. It's the same engine as the web app, driven by natural language. See the developer docs for the connection details.
PDFen publishes a Model Context Protocol (MCP) server so AI assistants like Claude and ChatGPT can convert and merge emails to PDF through chat. The assistant calls real conversion tools rather than guessing — producing an actual PDF file, attachments included, instead of a text approximation.
Attachments and forwarded emails are exactly where the built-in methods fall down — and where a real converter earns its place.
Attachments. Print to PDF renders only the message body; the attachment files are dropped. PDFen converts them instead: Office documents become PDF pages, while PDFs and images are included directly. You choose whether the output contains the body only, attachments only, or both — so a contract emailed as a Word file ends up in the same PDF as the message that sent it.
Forwarded ("wrapper") emails. When you forward a message, your forward becomes an envelope that contains the original email as an attachment. PDFen recognises this pattern: if a message's attachments are themselves emails, it treats the message as a wrapper and converts the original email inside — not the empty forwarding note. Forward five emails bundled in one, and you get five clean PDFs (or one merged file), each with its own attachments. That's what makes Method 5 reliable rather than a workaround.
There's no single best method — there's the best method for your situation. This table maps all seven to the job at hand.
Need | Best method | Software? |
One simple email, no attachments | Print to PDF (Method 1) | None |
One email with attachments | Forward to PDFen (5) or add-in (6) | None |
Merge several emails into one PDF | PDFen merge tool (4) | None |
Hundreds of emails / a full archive | Upload PST/OST/MBOX/OLM to PDFen (3) | None |
Convert without leaving Outlook | PDFen add-in (6) or Acrobat (2) | Add-in |
Repeated / scheduled conversion | PDFen API (7) | API token |
Do it from a chat assistant | ChatGPT/Claude + PDFen MCP (8) | Connector |
If you only ever save the odd email and never touch attachments, the built-in Print to PDF is genuinely enough. The moment attachments, merging, bulk archives, or compliance enter the picture, a dedicated converter saves real time — and unlike Adobe Acrobat's add-in, PDFen runs online, on any Outlook version, with a free tier to try first.
Microsoft removed PDF as a "Save as" type in the new Outlook for Windows. Its support page confirms "New Outlook doesn't include PDF as one of the defaults Save as types," leaving Print to PDF as the only built-in route — and that drops attachments (Microsoft Support). To keep attachments, upload or forward the email to a converter instead.
Not with native Outlook — each message prints to a separate file, and there's no "combine" option in classic, new, web, or Mac Outlook. To merge several emails into one page-numbered PDF, upload the .eml/.msg files (or a PST/ZIP archive) to PDFen's merge tool, arrange the order, and convert them in a single run.
Yes — but not with Print to PDF, which captures only the on-screen body. A converter that reads the raw email keeps them: PDFen turns Office attachments into PDF pages and embeds PDFs and images, with a setting to include the body, attachments, or both. Adobe Acrobat's add-in can also include attachments, but only in classic Outlook.
Because "print folder" prints the folder view — the list of message rows — not the contents of each email. It's a common surprise on Microsoft's forums. To convert the actual messages, export the folder as a PST and upload it to PDFen, which extracts every email and converts each one properly.
Open the email, choose File → Print (or ⌘P), then use the PDF dropdown → Save as PDF in the macOS print sheet. This relies on the system PDF engine, so it's more reliable than the Windows experience — but it still won't include attachments or merge messages. For those, upload the exported .eml to PDFen.
On their own, no — a chatbot has no rendering engine or mailbox access, so it can only summarise text you paste. Connected to PDFen's MCP server, though, Claude and ChatGPT can call real conversion tools and return an actual PDF, attachments included. It's the PDFen engine driven from a chat window.
Pick the method that fits: save a one-off with Print to PDF, or — for attachments, merging, archives, and compliance — convert your email to PDF with PDFen in your browser, free to try.
