Email Quarantine

Email Quarantine

Email Quarantine prevents email messages that have a high probability of being spam, phishing, or malware from going into your mailbox.

You will receive an email notification from Microsoft once a day if any emails have been quarantined that day. Emails are held in your quarantine for 30 days.

It is recommended that you check your email quarantine page regularly to review any messages that have been quarantined.
