End user reporting for Teams Calling (Preview)

  • Applies to: Microsoft Teams

In organizations with Microsoft Defender for Office 365 Plan 2 or Microsoft Defender XDR, admins can decide whether users can report malicious or suspicious calls in Microsoft Teams. Security admins can also get visibility into the Teams calls that users are reporting.

Users can report calls in Teams for security concern and calls that are not a security concern.

User reporting settings for Teams Calling – Security Concern

'Report call' reporting of calls in Teams is made of two separate settings:

  • In the Teams admin center: 'On' by default and controls whether users are able to report calls from Teams. When this setting is turned off, users can't report calls within Teams, so the corresponding setting in the Microsoft Defender portal is irrelevant.

  • In the Microsoft Defender portal: 'On' by default for new tenants. Existing tenants need to enable it. If user reporting of calls is turned on in the Teams admin center, it also needs to be turned on in the Defender portal for user reported calls to show up correctly.

Turn off or turn on user reporting for calling in Teams admin center

  1. Sign in to the Teams Admin Center at https://admin.teams.microsoft.com.
  2. In the left navigation of the Teams Admin Center, go to Voice > Calling policies.
  3. Select a policy.
  4. Turn on the setting: Report call.
  5. Select Save to apply the changes.
