How to Download an Outlook Email (and What That Actually Means)

Saving an email from Outlook sounds straightforward — and often it is — but "downloading" can mean a few different things depending on what you're trying to do. Are you saving a single email as a file? Exporting your entire mailbox? Archiving messages for backup? Each scenario involves a different approach, and the right one depends on your version of Outlook, your account type, and what you plan to do with the email afterward.

What Does "Downloading" an Outlook Email Actually Mean?

When most people ask how to download an email, they usually mean one of three things:

Saving a single email as a file (like a .msg or .eml file) to their computer
Saving an email as a PDF for sharing or record-keeping
Exporting a full mailbox or folder as a .pst file for backup or migration

These are meaningfully different operations. Saving one email to your desktop is a quick drag-and-drop task. Exporting your entire inbox involves Outlook's built-in export tools and produces a much larger file. Understanding which one applies to your situation determines which steps you'll follow.

How to Save a Single Email as a File

In Outlook Desktop (Windows)

The simplest method is drag and drop. Open Outlook, find the email you want, and drag it directly from your inbox to a folder on your desktop or in File Explorer. This saves it as a .msg file — a format that can be reopened in Outlook but isn't universally compatible with other email clients.

Alternatively:

Open the email
Go to File > Save As
Choose your destination folder
Select a file format — .msg is the default, but some versions also offer .txt or .html

In Outlook on Mac

Mac versions of Outlook save emails slightly differently. Dragging an email to your desktop typically produces an .eml file, which is more broadly compatible with other email clients like Apple Mail or Thunderbird.

In Outlook on the Web (OWA)

The web version of Outlook (used through a browser) has more limited local saving options. You can print to PDF as a workaround:

Open the email
Click the three-dot menu (more actions)
Select Print
In the print dialog, choose Save as PDF as your printer destination

This gives you a readable, shareable file, though it won't be re-importable as an email later.

How to Save an Email as a PDF 📄

Saving to PDF is useful when you need a static, shareable record — for legal documentation, expense reports, or just archiving a receipt. The process works similarly across platforms:

Windows: File > Print > Microsoft Print to PDF
Mac: File > Print > PDF (bottom-left dropdown)
Web: Print > Save as PDF (browser print dialog)

PDF saves the visual layout of the email, including formatting and images, but strips out the metadata that makes it re-importable as a functional email.

How to Export Outlook Emails in Bulk

If you need to download a large number of emails — say, for a backup, a legal hold, or switching email providers — the Export to .pst feature is the standard approach in Outlook for Windows.

Go to File > Open & Export > Import/Export
Select Export to a file
Choose Outlook Data File (.pst)
Select the folder (or entire mailbox) you want to export
Choose a save location and finish

A .pst file contains emails, calendar items, contacts, and attachments. It can be re-imported into Outlook later or opened as an archive.

⚠️ Note:.pst export is only available in the desktop version of Outlook for Windows. Outlook for Mac uses .olm files instead. The web version of Outlook doesn't support direct mailbox export to a local file — for that, IT administrators typically use compliance or eDiscovery tools tied to Microsoft 365.

Key Variables That Affect the Process

Factor	How It Affects the Process
Outlook version	Desktop vs. web vs. mobile have different capabilities
Operating system	Windows uses `.msg`/`.pst`; Mac uses `.eml`/`.olm`
Account type	Microsoft 365, Exchange, IMAP, and POP accounts behave differently
Volume of emails	Single emails vs. bulk exports require completely different methods
End goal	Archiving, sharing, legal use, or migration each call for different formats

What About Attachments?

Downloading an email and downloading its attachments are separate actions. If you only need a file someone sent you, you don't need to save the whole email — just open it and click the attachment to download it directly. Most Outlook versions show attachments at the top or bottom of the email with a clear download option.

If you want both the email body and its attachments preserved together, saving as .msg keeps them bundled. A PDF save will show inline images but won't always preserve downloadable attachments as functional files.

Syncing vs. Downloading in IMAP Accounts 🔄

One detail worth understanding: if your Outlook account uses IMAP (common with Gmail, Yahoo, or most third-party email providers), emails aren't truly "downloaded" by default — they're synced. The messages live on the server, and Outlook shows you a local copy that stays in sync.

With POP3 accounts, emails are actually pulled down to your device and (by default) removed from the server. This distinction matters if you're trying to work offline, back up messages, or understand where your emails "live."

The method that works best for downloading Outlook emails ultimately comes down to which version of Outlook you're using, what account type you're connected to, and what you need the saved email to do once it's off the server.
