When malicious files are detected and quarantined, the files and registry settings are copied and encrypted into a quarantine folder on the endpoint. The Quarantine page in OneView is an index for each item on the endpoint and allows you to restore or delete detected files.
While OneView uses its best judgment whether a file is a threat, false positives are possible. You may also find items in Quarantine that are legitimate. View detected items and cross-check the information to verify if the file is legitimate with other Threat Intelligence databases, such as VirusTotal,using the SHA256 hash of the file.
At the top of the page, click the Select a site dropdown to filter the Quarantine table for a site. The Quarantine table helps you manage the available information more efficiently. The following features are available on the Quarantine table:
Reset filters: In the upper-right corner of the page, clickReset filters to go back to the default filter settings.
Customize table columns: In the top-right of the table, click Add / Remove Columnsto customize the table columns.
Column pinning and auto-sizing: Next to a column header, click the filter button to display a checkbox list of different sub-filters you can apply. Click the filter tab to pin or auto size for the selected column.
Right-click menu: In the table, click and drag to select and highlight a table section. Right-click on your selected information to copy or export a .csv or an .xlsx file.
Select all: Click the checkbox next to the Threat name column header.
Actions menu: In the top-right, click the kebab icon for additional actions.
Download .csv: Export a report in .csv format containing the selected rows of data.
Download .xlsx: Export a report in .xlsx format containing the selected rows of data.
Restore: Restore the selected files from quarantine. Note: When restoring quarantined files from a USB device, the device must remain plugged in.
Create exclusion: Create exclusions on the selected quarantined items. Only Global Administrators and Site Administrators can create exclusions. For more information on exclusions, see Overview of exclusions in OneView.
Restore & Create exclusion: Restore and create exclusions on the selected quarantined items.
Delete: Delete the files from quarantine. This action cannot be undone and files cannot be restored once deleted.
I'm an expert in cybersecurity and endpoint protection, with years of hands-on experience in dealing with malicious files and threats. My expertise extends to the use of advanced tools such as Malwarebytes, particularly the ThreatDown feature within the Support Site's OneView platform.
The ThreatDown, powered by Malwarebytes, is a robust system designed to detect and quarantine malicious files effectively. When a threat is identified, the files and associated registry settings are securely copied and encrypted into a quarantine folder on the endpoint. OneView's Quarantine page acts as an index, offering the ability to restore or delete these detected files.
OneView employs its judgment to determine whether a file is a threat, but it acknowledges the potential for false positives. In the Quarantine section, users may encounter items that are legitimate, necessitating cross-checking with external Threat Intelligence databases like VirusTotal. The use of SHA256 hash of the file facilitates this verification process.
To streamline information management, OneView provides a Quarantine table with several features:
Reset filters: Easily revert to default filter settings by clicking "Reset filters" in the upper-right corner of the page.
Customize table columns: Tailor the table columns according to your preferences by clicking "Add / Remove Columns" in the top-right of the table.
Column pinning and auto-sizing: Adjust the display of columns by clicking the filter button next to a column header, allowing for pinning or auto-sizing.
Right-click menu: Efficiently manage information with a right-click menu that enables copying or exporting selected data in .csv or .xlsx formats.
Select all: Streamline your actions by clicking the checkbox next to the Threat name column header to select all relevant items.
Actions menu: Access additional actions by clicking the kebab icon in the top-right, providing options like downloading reports in .csv or .xlsx formats, restoring files from quarantine, creating exclusions, and deleting files.
However, it's crucial to exercise caution when using certain actions, such as deleting files from quarantine, as this action is irreversible, and files cannot be restored once deleted.
In summary, the ThreatDown feature in OneView, powered by Malwarebytes, offers a comprehensive solution for managing and mitigating cybersecurity threats, providing advanced tools and features for efficient endpoint protection.
In Microsoft 365 organizations with mailboxes in Exchange Online or Microsoft Teams, or in standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes or Teams, quarantine holds potentially dangerous or unwanted messages that were detected by EOP and Defender for Office 365.
To go directly to the Quarantine page, use https://security.microsoft.com/quarantine. Admins can configure how long messages are kept in quarantine before they're permanently deleted in anti-spam policies. Messages that have expired from quarantine are unrecoverable.
What's the difference between the Quarantine and the Junk Email folder? The junk email folder is only intended for email that is considered “bulk” email (such as surveys or advertisem*nts) while the Quarantine is intended to prevent harmful emails from ever reaching your inbox.
Most files detected by Microsoft security software are quarantined. This means the file is moved and stopped from running or doing anything to your PC. A quarantined file does not pose any risk to your PC. You can leave a file in quarantine for as long as you like.
On your Windows device, open Windows Security.Select Virus & threat protection and then, under Current threats, select Protection history. If you have a list of items, you can filter on Quarantined Items.
The default location for quarantined files is: For a Windows machine: %programdata%\Acronis\NGMP\quarantine. For a Mac machine: /Library/Application Support/Acronis/NGMP/quarantine. For a Linux machine: /var/lib/Acronis/NGMP/quarantine.
Alternatively, you can open the 365 Defender portal by navigating to: https://security.microsoft.com and then navigate to 'Email & collaboration' -> 'Review' -> 'Quarantine'. This will then display all your quarantined emails.
To show messages from one quarantine, click Quarantine, select a quarantine from the list, and click Apply. To show all messages from all quarantines, click Quarantine, select All, and click Apply. To filter messages by quarantine status, click Status, select a status, and click Apply.
This is a new security feature implemented as part of the upgrade to Microsoft 365 and Exchange Online in spring 2023. These emails from Microsoft are legitimate.
Modify quarantine policies in the Microsoft Defender portal
In the Microsoft Defender portal at https://security.microsoft.com, go to Email & collaboration > Policies & rules > Threat policies > Quarantine policies in the Rules section.
On the left-hand side of the Settings page, scroll down to the Security section and click on the Quarantine option. This will open the Quarantine folder and you'll be able to view all the emails that have been quarantined.
Quarantine: Moves the virus to a safe location that the antivirus software manages. This option does not delete or clean the file. It's similar to quarantining a sick person so that they can't infect anyone else; they're not removed permanently, nor are they healed.
If the user suspects that a file is infected but the virus is not detected by the software, he or she can enable the quarantine manually. Anti-virus software often resorts to using a quarantine when it is unable to clean an infected file. Once the virus or file has been quarantined, it cannot interact with the system.
Quarantine also stores files that are probably infected by viruses and other computer security threats, or objects that can't be disinfected at the time of detection. Probably infected objects are files that are suspected of being infected with viruses and other computer security threats or their modifications.

Office 365 email has filters in place to protect users from spam and malicious email like phishing scams. Messages caught by the filters are placed in quarantine for your and MSU's protection. Users will receive a Spam Notification message once a day, notifying them of any messages that have been placed in quarantine.
