Protection against phishing, malware, and other threats targeting email and collaboration tools in Microsoft 365
Yes. Disregard it if it is a Defender Prime Express renewal email. That message is identified as a scam.
Safe actions:
- Do not call any phone number in the email.
- Do not click links or open attachments.
- If wanting to verify, open a new browser tab and sign in to the relevant account directly using a saved favorite or a web search, not the email.
- Report the message as spam or phishing in the mail client, or delete it.
Extra warning signs include mismatched sender domains, suspicious links, unexpected attachments, and Outlook warnings such as an unverified sender banner, a ? sender image, or a via tag showing a different actual sender.
