Creating a custom quarantine policy in Microsoft Defender for Office 365 involves configuring advanced threat protection settings to protect your organization’s email environment.
To create a Custom Quarantine policy in Microsoft Defender for Office 365, you can follow these general steps:

2.Expand the Email & collaboration on the Microsoft Defender page and select Policies & rules.
3.Select Threat policies on the Policies & rules page.
