Thanks for reaching out Manuel. I understand your concern. Although the email appears to come from Microsoft, its content seems suspicious. Microsoft does send Teams notifications from its legitimate M365 email domain, but scammers are using realistic-looking Teams invites to send fake payment requests and phone numbers. The phrase call us now is a phishing tactic. Microsoft warns users to proceed only if they know the sender.
Do not click any links or call the number provided. Open Teams to see if you were added to a team you know. Report the email as phishing in Outlook and then delete it. If you clicked anything, change your Microsoft account password, ensure multi-factor authentication is enabled, and check recent account activity.
You can reach Microsoft support through their official channels in a few ways:
Go to Microsoft Support Contact Page and sign in with your account. From there, you can choose your product and start a live chat or request a call back from a Microsoft specialist.
You can also use the Get Help app on Windows or access it via your browser for guided troubleshooting and direct support options. If you prefer phone support, Microsoft lists official customer service numbers by region on their Customer Service Phone Numbers page.
All the best,
Rez
