Is this Teams or Microsoft, Official Mail id? or Spam id?

Looks like something that will be used in a spam/phish attempt, thread carefully. A quick check shows that it's an AWS-registered domain, so definitely not something Microsoft would use.

This is a domain used by KnowBe4 phishing challenge emails. Clicking it would send an alert to your ITSec person to put you through more KnowBe4 training. In the message, goto File -> Info -> Properties, then scroll down in the 'Internet Headers' section and you should see something like "Received: from". it was 28 lines down in the headers for me.
