Microsoft Teams Introduces ‘Report a Call’ Feature to Combat Phishing and Scam Calls

CyberDefender 3 mins0

Microsoft is rolling out a new “Report a Call” feature in Microsoft Teams to help users flag one-to-one calls that feel suspicious or unwanted. Think phishing attempts, scam calls, or anything that just doesn’t pass the smell test.

How the feature works

If you get a call that seems off, you can report it directly from your call history in Teams on Windows, Mac, or the web.
Just click More options next to the call and select Report a Call. No extra tools, no long forms.

What information gets shared

When a call is reported, Teams sends limited metadata to both Microsoft and your organization. This includes things like:

  • Call timestamps
  • Call duration
  • Caller ID
  • Participant Teams IDs

No call content is shared — the goal is to spot patterns of abuse, not listen in.

Rollout timeline

  • Targeted Release (early adopters): mid-March 2026
  • General Availability (global rollout): late April 2026

So you may see it sooner if your org is on an early release channel.

Admin controls

The feature will be enabled by default, but IT admins aren’t locked in. They can turn it off anytime through the Teams Admin Center under Calling settings.

How reports are used by security teams

  • Organizations with Microsoft Defender for Office 365 (Plan 1 or Plan 2) or Defender XDR can view detailed insights in the Microsoft Defender portal.
  • Organizations without those licenses will still get basic reporting through the Teams Admin Center under Protection Reports.

Why this matters

Until now, reporting shady calls in Teams wasn’t easy — which meant many organizations had little visibility into voice-based phishing (vishing) and scam attempts. This feature closes that gap by letting users report problems right where they happen, helping security teams respond faster and smarter.

Part of a bigger security push

The call-reporting feature is just one piece of a larger Teams security upgrade, including:

  • Brand impersonation warnings for calls pretending to be trusted companies
  • Ongoing improvements to call quality, productivity, and collaboration
  • Increased focus on stopping abuse as attackers target Teams messages and calls more frequently
