Improve spam filtering
There’s a useful add-in for Microsoft Outlook that works well with Microsoft 365 hosted email services. Its the Report Phishing extension. You can download it from https://appsource.microsoft.com
Once installed you get an extra button on the ribbon at the top right. If a phishing or spam email arrives in your inbox, highlight it and click the Report Phishing button. This will submit the details to Microsoft, helping them remove the emails and track sources of junk.
