Reporting a fake teams account

Hi,

Thank you for sharing your question. I understand how unsettling it can be when someone pretends to be a celebrity or someone you recognize. This kind of impersonation is taken seriously by Microsoft and falls under their external spam, phishing, or brand impersonation protections in Teams.

Teams includes built-in safeguards to detect and alert you when an external user might be impersonating someone or a known brand. You may see a warning when accepting chat requests from external accounts, which helps you proceed with caution. If you suspect an account is fake, you should block the user to prevent further messages and report the impersonation through Teams. This helps Microsoft investigate and take action.

You can report a concerning message directly by hovering over it, selecting More options (…) and choosing Report this message. You’ll then select a category such as “Security risk – Spam, phishing, or malicious content” and submit the report. Additionally, if impersonation extends beyond messages—such as profile or account misuse—you can escalate the report to Microsoft via their Security Response Center at https://msrc.microsoft.com/report/.

I hope this helps.

Best Regards,

Noel
