The user is experiencing an issue where all incoming emails are unexpectedly routed to the Junk Email folder instead of the inbox.

How to Stop Outlook from Sending All Incoming Email to the Junk Folder

Product: Microsoft Outlook
Device & OS: not provided
Scenario: Receiving regular incoming emails but finding them automatically moved to the junk folder despite disabled filters.
Observed behavior: Outlook moves every incoming message to the Junk Email folder even when blocked addresses are not configured and junk filters appear to be disabled.

Before you start

Before modifying your settings, briefly check if the emails in your Junk folder are from known contacts or if they are genuinely spam, as this helps determine whether the issue is a strict filter setting or a rogue inbox rule.

Solution 1Recommended

Disable Strict Safe Senders Setting in Outlook on the Web

Ensure Outlook is not configured to strictly trust only the senders listed in your Safe Senders list.

If you use Outlook on the web, a specific filter setting might be forcing all unknown senders directly into your Junk Email folder. Disabling this strict filtering rule usually restores normal inbox delivery.

Access Settings

Navigate to Junk Email

Click on 'Junk email' from the secondary menu to access your spam filtering options.

Disable Strict Filtering

Scroll down to the 'Filters' section and verify that the option 'Only trust email from addresses in my Safe senders and domains list and Safe mailing lists' is unchecked. Save your changes.

Disable Strict Safe Senders Setting in Outlook on the Web

Check Your Inbox: After saving this setting, new incoming emails from safe or neutral senders should correctly land in your primary Inbox.

Solution 2

Adjust Junk Email Options in Outlook for Windows

Lower the junk email protection level in the Outlook desktop application.

Solution 3

Review Inbox Rules and Blocked Senders

Remove any accidental block lists or rogue rules that might be rerouting your emails.

Frequently Asked Questions

Why are emails from my safe senders still going to junk?

This can happen if a conflicting inbox rule is moving them, or if your organization's server-level spam filter determines the email is malicious, overriding your personal Safe Senders list.

Can connected accounts cause emails to go to the junk folder?

Yes, if you have multiple email accounts connected to Outlook, the spam filtering rules of the original email provider (such as Gmail or Yahoo) might flag the message before it reaches your Outlook inbox.

How do I stop emails from a specific domain from going to junk?

You can whitelist the domain by adding it to your Safe Senders list. Go to Junk Email Options > Safe Senders, click Add, type the domain (e.g., @example.com), and click OK.

What should I do if my organization's policies are blocking emails?

If you are using a work or school Exchange account and adjusting local settings does not resolve the issue, contact your IT administrator. They may need to adjust the organization-level Exchange spam filter policies.
