Thank you for letting me know.
Since these are already going to Junk and you’re using strict filtering, this means Outlook is catching most of them, but the senders are constantly changing their tricks to get through. Unfortunately, that’s why rules and blocks don’t always work long-term.
A few things you can still try:
- In Junk Email settings, make sure Safe senders and domains only contains people you really trust. Too many entries there can weaken filtering: https://support.microsoft.com/office/add-recipients-to-the-safe-senders-list-in-outlook-be1baea0-beab-4a30-b968-9004332336ce
- Keep reporting these as Phishing (not just Junk) when possible. This helps Microsoft improve server-side filtering. "Phishing and suspicious behavior in Outlook" https://support.microsoft.com/office/phishing-and-suspicious-behavior-in-outlook-0d882ea5-eedc-4bed-aebc-079ffa1105a3
- Avoid opening or clicking anything in these messages, even in Junk.
About checking Junk for real emails, sadly, that’s still necessary when using strict filtering. There isn’t a perfect way to stop all spam without risking missed messages.
Have you used this email address to sign up for any new services, websites, or downloads in the past few months? A spike like this often means the address was shared or leaked somewhere.
