+# Contact Microsoft Defender support
+
+Microsoft Defender support process is designed to help you find solutions to common problems and submit support cases to the Microsoft support team.
+
+## Prerequisites
+
+You must meet the following requirements before you can open a support case:
+
+- You must have either the **Service Support Administrator or Helpdesk Administrator role**.
+
+For more information on role permissions, see [Security Administrator permissions](/azure/active-directory/roles/permissions-reference#security-administrator).
+
+For more information on admin roles, see [About admin roles](/microsoft-365/admin/add-users/about-admin-roles?view=o365-worldwide&preserve-view=true).
+
+- You must have a Microsoft Defender for Endpoint Plan 1 or Plan 2 license. If your organization uses only Defender for Servers Plan 1 or Plan 2, you'll also need at least one Defender for Endpoint license to open a support case.
+
+
+## Access the widget
+
+
+1. Select the question mark on the top right of the Defender portal page
