+# Quickly configure Microsoft Teams protection in Microsoft Defender for Office 365 Plan 2
+
+Even if you aren't using Microsoft Defender for Office 365 Plan 2 for email protection, you can still use it for Microsoft Teams protection.
+
+This article contains the quick steps to turn on and configure Defender for Office 365 protection for Microsoft Teams.
+
+## What do you need to know before you begin?
+
+- You open the Microsoft Defender portal at <https://security.microsoft.com>.
+
+- You need to be assigned permissions before you can do the procedures in this article. You have the following options:
+  - [Microsoft Defender XDR Unified role based access control (RBAC)](/defender-xdr/manage-rbac) (If **Email & collaboration** \> **Defender for Office 365** permissions is :::image type="icon" source="media/scc-toggle-on.png" border="false"::: **Active**. Affects the Defender portal only, not PowerShell): **Authorization and settings/Security settings/Core Security settings (manage)**.
+  - [Email & collaboration permissions in the Microsoft Defender portal](mdo-portal-permissions.md) and [Exchange Online permissions](/exchange/permissions-exo/permissions-exo):
+    - Membership in the **Organization Management** or **Security Administrator** role groups in Email & collaboration permissions <u>and</u> membership in the **Organization Management** role group in Exchange Online permissions.
+  - [Microsoft Entra permissions](/entra/identity/role-based-access-control/manage-roles-portal): Membership in the **Global Administrator**<sup>\*</sup> or **Security Administrator** roles gives users the required permissions _and_ permissions for other features in Microsoft 365.
+
+    > [!IMPORTANT]
+    > <sup>\*</sup> Microsoft recommends that you use roles with the fewest permissions. Using lower permissioned accounts helps improve security for your organization. Global Administrator is a highly privileged role that should be limited to emergency scenarios when you can't use an existing role.
+
+- Allow up to 30 minutes for a new or updated policy to be applied.
+
+- For more information about licensing requirements, see [Licensing terms](/office365/servicedescriptions/office-365-advanced-threat-protection-service-description#licensing-terms).
+
+- Teams integration deployment is part of the overall deployment process of Defender for Office 365. For more information, see [Pilot and deploy Defender for Office 365](/defender-xdr/pilot-deploy-defender-office-365?toc=%2Fdefender-office-365%2FTOC.json&bc=%2Fdefender-office-365%2Fbreadcrumb%2Ftoc.json).
+
+## Step 1: Verify Safe Attachments integration for Microsoft Teams
+
+For complete instructions, see [Turn on Safe Attachments for SharePoint, OneDrive, and Microsoft Teams](safe-attachments-for-spo-odfb-teams-configure.md).
+
+1. In the Microsoft Defender portal, go to the **Safe Attachments** page at <https://security.microsoft.com/safeattachmentv2>.
+2. On the **Safe Attachments** page, select :::image type="icon" source="media/m365-cc-sc-gear-icon.png" border="false"::: **Global settings**.
+3. In the **Global settings** flyout that opens, go to the **Protect files in SharePoint, OneDrive, and Microsoft Teams** section to verify **Turn on Defender for Office 365 for SharePoint, OneDrive, and Microsoft Teams** is :::image type="icon" source="media/scc-toggle-on.png" border="false"::: **On**.
+
+   If the value is :::image type="icon" source="media/scc-toggle-off.png" border="false"::: **Off**, move the toggle to :::image type="icon" source="media/scc-toggle-on.png" border="false"::: **On**, and then select **Save**.
+
+> [!TIP]
+>
+> - You can't restrict Safe Attachments for SharePoint, OneDrive, and Microsoft Teams to Microsoft Teams only.
+> - You can't scope Safe Attachments for SharePoint, OneDrive, and Microsoft Teams to specific users. It's on or off for everyone.
+
+## Step 2: Verify Safe Links integration for Microsoft Teams
+
+For complete instructions, see [Use the Microsoft Defender portal to modify custom Safe Links policies](safe-links-policies-configure.md#use-the-microsoft-defender-portal-to-modify-custom-safe-links-policies).
+
+1. In the Microsoft Defender portal, go to the **Safe Links** page at <https://security.microsoft.com/safelinksv2>.
+2. On the **Safe Links** page, verify Teams integration is turned on in any custom policies (policies with a numerical **Priority** value) by doing the following steps:
+   1. Select the policy by clicking anywhere in the row other than the check box next to the first column.
+   2. In the **Teams** section of the **Protection settings** section in the details flyout that opens, verify the value is **On: Safe Links checks a list of known, malicious links when users click links in Microsoft Teams. URLs are not rewritten**.
+
+      If the value is **Off**, select **Edit protection settings** at the bottom of the **Protection settings** section. In the **URL & click protection settings** flyout that opens, select the check box in the **Teams** section, select **Save**, and then select **Close**.
+
+   Repeat these steps on every custom Safe Links policy.
+
+> [!TIP]
+> Teams integration is on in the [Built-in protection preset security policy](preset-security-policies.md), but any other Safe Links policies [take precedence](preset-security-policies.md#order-of-precedence-for-preset-security-policies-and-other-policies) over the Built-in protection preset security policy (as shown in the order they're listed on the **Safe Links** page).
+
+## Step 3: Configure Zero-hour auto purge (ZAP) for Microsoft Teams
+
+For complete instructions, see [Configure ZAP for Teams protection in Defender for Office 365 Plan 2](mdo-support-teams-about.md#configure-zap-for-teams-protection-in-defender-for-office-365-plan-2).
+
+1. In the Microsoft Defender portal, go to the **Microsoft Teams protection** page at <https://security.microsoft.com/securitysettings/teamsProtectionPolicy>.
+
+2. On the **Microsoft Teams protection** page, verify the toggle in the **Zero-hour auto purge (ZAP)** section is :::image type="icon" source="media/scc-toggle-on.png" border="false"::: **On**.
+
+   If the value is :::image type="icon" source="media/scc-toggle-off.png" border="false"::: **Off**, move the toggle to :::image type="icon" source="media/scc-toggle-on.png" border="false"::: **On**, and then select **Save**.
+
+> [!TIP]
+> When ZAP for Microsoft Teams is turned on, you can use **Exclude these participants** on the **Microsoft Teams protection** page to exclude users from Teams protection. For more information, see [Configure ZAP for Teams protection in Defender for Office 365 Plan 2](mdo-support-teams-about.md#configure-zap-for-teams-protection-in-defender-for-office-365-plan-2).
+
+## Step 4: Configure user reported settings for Microsoft Teams
+
+For complete instructions, see [User reported message settings in Microsoft Teams](submissions-teams.md).
+
+1. In the Teams admin center, go to the **Messaging policies** page at <https://admin.teams.microsoft.com/policies/messaging>.
+
+2. On the **Manage policies** tab of the **Messaging policies** page, verify that the **Manage policies** tab is selected, and do either of the following actions to edit the appropriate policy (the **Global (Org-wide) default** policy for all users or a custom policy for specific users):
+   - Select the link in the **Name** column.
+   - Select the policy by clicking anywhere in the row other than the **Name** column, and then select :::image type="icon" source="media/m365-cc-sc-edit-icon.png" border="false"::: **Edit**.
+
+3. In the policy details page that opens, find the **Report a security concern** toggle, and verify the value is :::image type="icon" source="media/scc-toggle-on.png" border="false"::: **On**.
+
+   If the value is :::image type="icon" source="media/scc-toggle-off.png" border="false"::: **Off**, move the toggle to :::image type="icon" source="media/scc-toggle-on.png" border="false"::: **On**, and then select **Save**.
+
+4. In the Microsoft Defender portal, go to the **User reported settings** page at <https://security.microsoft.com/securitysettings/userSubmission>.
+
+5. On the **User reported settings** page, go to the **Microsoft Teams** section, and verify **Monitor reported messages in Microsoft Teams** is selected.
+
+   If it's not selected, select the check box, and then select **Save**.
