# 5 - Junk email folder and administrative quarantine

Last updated Apr 17, 2026|Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/cloudflare-one/email-security/setup/pre-delivery-deployment/prerequisites/m365-email-security-mx/use-cases/five-junk-admin-quarantine/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

In this tutorial, you will learn to deliver `BULK` messages to the user's junk email folder, and `MALICIOUS`, `SPAM`, and `SPOOF` messages to the Administrative Quarantine (this requires an administrator to release the emails).

## Configure anti-spam policies

To configure anti-spam policies:

1. Open the [Microsoft 365 Defender console ↗](https://security.microsoft.com/).
2. Go to **Email & collaboration** > **Policies & rules**.
3. Select **Threat policies**.
4. Under **Policies**, select **Anti-spam**.
5. Select the **Anti-spam inbound policy (Default)** text (not the checkbox).
6. In **Actions**, scroll down and select **Edit actions**.
7. Set the following conditions and actions (you might need to scroll up or down to find them):

- **Spam**: *Move messages to Junk Email folder*.
- **High confidence spam**: *Quarantine message*.
  - **Select quarantine policy**: \_AdminOnlyAccessPolicy\_.
- **Phishing**: *Quarantine message*.
  - **Select quarantine policy**: \_AdminOnlyAccessPolicy\_.
- **High confidence phishing**: *Quarantine message*.
  - **Select quarantine policy**: \_AdminOnlyAccessPolicy\_.
- **Retain spam in quarantine for this many days**: Default is 15 days. Email security recommends 15-30 days.
  - Select the spam actions in the above step.

8. Select **Save**.

## Create transport rules

To create the transport rules that will send emails with certain [disposition](https://developers.cloudflare.com/cloudflare-one/email-security/reference/dispositions-and-attributes/#dispositions) to Email security:

1. Open the new [Exchange admin center ↗](https://admin.exchange.microsoft.com/#/homepage).
2. Go to **Mail flow** > **Rules**.
3. Select **Add a Rule** > **Create a new rule**.
4. Set the following rule conditions:
   - **Name**: *Email security Deliver to Junk Email folder\`*.
   - **Apply this rule if**: *The message headers* > *includes any of these words*.
     - **Enter text**: `X-CFEmailSecurity-Disposition` > **Save**.
     - **Enter words**: `BULK` > **Add** > **Save**.
   - **Apply this rule if**: Select **+** to add a second condition.
   - **And**: *The sender* > *IP address is in any of these ranges or exactly matches* > enter the egress IPs in the [Egress IPs](https://developers.cloudflare.com/cloudflare-one/email-security/setup/pre-delivery-deployment/egress-ips/) page.
   - **Do the following** - *\_Modify the message properties\_ > \_Set the Spam Confidence Level (SCL)\_ > \_5\_*.
5. Select **Next**.
6. You can use the default values on this screen. Select **Next**.
7. Review your settings and select **Finish** > **Done**.
8. Select the rule Email security Deliver to Junk Email folder\` you have just created, and **Enable**.

    - **Do the following**: *\_Redirect the message to\_ > \_hosted quarantine\_*.
11. Select **Next**.
