Most spam email will continue to be sent to the Junk folder in Outlook which you should continue to review for any legitimate messages.

Email deemed to be high-risk will be quarantined -- you will be emailed a daily digest of any quarantined email from quarantine@messaging.microsoft.com. You only need to take action if legitimate email has been quarantined.

Email will be quarantined for 30 days, after which it will be deleted.
