Defender for Endpoint has recently upgraded the support process to offer a more modern and advanced support experience.

The new widget allows customers to:

  • Find solutions to common problems
  • Submit a support case to the Microsoft support team


It's important to know the specific roles that have permission to open support cases.

At a minimum, you must have a Service Support Administrator OR Helpdesk Administrator role.

For more information on which roles have permission, see Security Administrator permissions.

For general information on admin roles, see About admin roles.

Access the widget

Accessing the new support widget can be done in one of two ways:

  1. Clicking on the question mark on the top right of the portal and then clicking on "Microsoft support":

  2. Clicking on the Need help? button in the bottom right of the Microsoft Defender portal:
