How to Access Your Spam Folder in Outlook

Finding emails that got incorrectly filtered, checking what Outlook flagged as suspicious, or just doing routine inbox hygiene — whatever the reason, knowing how to navigate to your spam folder in Outlook is a basic skill that trips up more people than you'd expect. The folder exists under a different name, behaves differently depending on how you're accessing Outlook, and works through a filtering system that isn't always obvious.

Here's a clear breakdown of how it all works.

What Outlook Calls the Spam Folder

Outlook doesn't label it "Spam." Instead, it's called the Junk Email folder. This is true across the desktop app, the web version, and mobile. If you've been hunting for a folder called Spam, that's likely why you couldn't find it — it's sitting right there under a different name.

The Junk Email folder functions as Outlook's catch-all for messages its filters flag as potentially unwanted. Some of those flags are accurate. Others aren't — and legitimate emails end up there regularly, which is why checking it periodically matters.

Accessing Junk Email on Outlook Desktop (Windows and Mac)

On the Outlook desktop application, the Junk Email folder lives in your left-hand folder panel — the same sidebar where you see your Inbox, Sent Items, Drafts, and Deleted Items.

To find it:

1. Look at the folder list on the left side of the Outlook window
2. Scroll down past your main folders
3. Click Junk Email

If you don't see it immediately, your folder list may be collapsed. Click the arrow or expand icon next to your account name to reveal all subfolders.

On Mac, the layout is nearly identical — the Junk folder appears in the same left-panel hierarchy. In some configurations, especially with IMAP accounts connected through Outlook, the folder might display as "Spam" rather than "Junk Email," depending on what the mail server sends through.

Accessing Junk Email on Outlook Web (Outlook.com)

On Outlook.com (the browser-based version), the process is straightforward:

1. Sign in at outlook.com
2. Look at the left navigation panel
3. Click Junk Email in the folder list

If you don't see it in the main list, click More at the bottom of the folder panel to expand all available folders. Junk Email will appear there.

The web version also includes a Sweep and Filter toolbar when you're inside the Junk Email folder, giving you options to bulk-delete, mark as not junk, or block senders directly from that view.

Accessing Junk Email on the Outlook Mobile App 📱

On the Outlook mobile app (iOS or Android), folder navigation works slightly differently:

1. Open the app and tap the hamburger menu (three horizontal lines) in the top-left corner
2. This opens the folder list for your account
3. Scroll down to find Junk Email and tap it

If you manage multiple accounts in the app, each account has its own folder hierarchy. Make sure you're looking at the right account's folder list before concluding the folder doesn't exist.

How Outlook's Junk Email Filter Works

Outlook uses a built-in Junk Email Filter that evaluates incoming messages based on several signals: sender reputation, message content, header data, and behavioral patterns. It doesn't use a single fixed rule — it weighs multiple factors simultaneously.

The filter operates on a spectrum of sensitivity:

You can adjust this in the desktop app under Home → Junk → Junk Email Options, or in Outlook.com under Settings → Mail → Junk email.

Marking Emails as Not Junk

When you find a legitimate email in Junk Email, you have a couple of options:

• Right-click (on desktop) and select Mark as Not Junk — this moves the message to your Inbox and optionally adds the sender to your Safe Senders list
• In Outlook.com, select the email and use the Not junk button in the toolbar
• On mobile, tap and hold the message, then select Move to Inbox or the equivalent option in your version of the app

Doing this consistently helps Outlook learn your preferences over time, though the degree to which individual actions retrain the filter varies.

Variables That Affect Where You Find the Folder

Not everyone's Outlook setup looks the same, and a few factors shape the experience:

• Account type: Microsoft 365, Exchange, Outlook.com, Gmail added via IMAP, and other third-party accounts all behave slightly differently. IMAP accounts may show a server-side Spam folder alongside or instead of Outlook's native Junk Email folder.
• Outlook version: Older versions of the desktop app have a different interface layout than current Microsoft 365 builds. The folder still exists, but the navigation path may look different.
• Organization IT policies: If you're using Outlook through a workplace or school, your IT department may have configured additional filtering layers — including quarantine folders that aren't visible in Outlook at all, managed through a separate admin portal.
• Exchange Online Protection: Business Microsoft 365 accounts often route certain messages to a quarantine held at the server level, not to your local Junk Email folder. Accessing those requires going through the Microsoft 365 Defender portal or following a quarantine notification email.

Why Legitimate Emails End Up in Junk 🔍

The Junk Email filter makes mistakes, and it's worth understanding why:

• Mailing list emails often carry patterns similar to bulk spam
• Emails with lots of images and few words can trigger content-based filters
• Unfamiliar senders — even legitimate ones — score lower on trust signals
• Certain subject line patterns (all caps, excessive punctuation, specific phrases) raise filter scores

None of these mean the email is actually spam — just that it matched patterns the filter associates with spam. This is why reviewing Junk Email occasionally, rather than ignoring it entirely, tends to prevent missed messages.

The right approach to Outlook's Junk Email folder — how often to check it, whether to adjust filter sensitivity, and how to handle quarantined messages — depends heavily on whether you're using a personal account, a business account with IT-managed filtering, or a hybrid setup with multiple email providers connected to a single Outlook client. Each of those scenarios involves meaningfully different tools and access points.
