Our reviewer read version 0.0.1 — the most recent version we have reviewed — and found no malicious behaviour. The version shown here has not been individually reviewed yet.

What our analysis found

Outlook Classroom Email, used by 100,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in April 2025.

The extension contains no executable JavaScript; only a static declarativeNetRequest rule that redirects Google Classroom email links to Outlook. This matches the stated description and uses minimal permissions. No data collection, exfiltration, or malicious behavior is present. The third-party risk score flags are likely false positives due to the generic nature of the permission set.
