Jul 14, 2020 Act on quarantined risks or threats. Quarantined items are isolated from the rest of your computer so that they cannot spread or infect your computer. If you have an item that you think is infected, but is not identified as a risk by Norton, you can manually put the item in Quarantine.

In Microsoft 365 organizations with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes, quarantine holds potentially dangerous or unwanted messages. For more information, see Quarantined email messages in EOP.
Admins can view, release, and delete all types of quarantined messages for all users. Only admins can manage messages that were quarantined as malware, high confidence phishing, or as a result of mail flow rules (also known as transport rules). Admins can also report false positives to Microsoft.
Admins in organizations with Office 365 Advance Threat Protection (Office 365 ATP) can also view, download, and delete quarantined files in SharePoint Online, OneDrive for Business, and Microsoft Teams.
You view and manage quarantined messages in the Security & Compliance Center or in PowerShell (Exchange Online PowerShell for Microsoft 365 organizations with mailboxes in Exchange Online; standalone EOP PowerShell for organizations without Exchange Online mailboxes).
What do you need to know before you begin?
To open the Security & Compliance Center, go to https://protection.office.com. To open the Quarantine page directly, go to https://protection.office.com/quarantine.
To connect to Exchange Online PowerShell, see Connect to Exchange Online PowerShell. To connect to standalone EOP PowerShell, see Connect to Exchange Online Protection PowerShell.
You need to be assigned permissions before you can manage the quarantine as an admin. The permissions are controlled by the Quarantine role in the Security & Compliance Center. By default, this role is assigned to the Organization Management (Global admins), Quarantine Administrator, and Security Administrator role groups in the Security & Compliance Center. For more information, see Permissions in the Security & Compliance Center.
Quarantined messages are retained for a default period of time before they're automatically deleted:
Messages quarantined by anti-spam policies (spam, phishing, and bulk email): 30 days. This is the default and maximum value. To configure this value, see Configure anti-spam policies.
Messages that contain malware: 15 days.
When a message expires from quarantine, you can't recover it.

Release messages: The options are the same as when you release a single message, except you can't select Release messages to specific recipients; you can only select Release message to all recipients or Release messages to other people.
Note
Consider the following scenario: [email protected] sends a message to [email protected] and [email protected]. Gmail bifurcates this message into two copies that are both routed to quarantine as phishing in Microsoft. An admin releases both of these messages to [email protected]. The first released message that reaches the admin mailbox is delivered. The second released message is identified as duplicate delivery and is skipped. Message are identified as duplicates if they have the same message ID and received time.
