Defender of XDR - Quarantine - Lack of filter/search options

Hi, I agree this is a real pain point, especially when quarantine review is a daily operational task. As a workaround, I’d use Explorer or Advanced Hunting where available to narrow down message sender, recipient, domain, subject, and delivery details before taking action in quarantine. It is not as smooth as having proper quarantine filters, but it can reduce the amount of manual checking. I’d also submit this through the Defender portal feedback option, because filtering by sender domain and recipient domain would be a very reasonable feature request for security teams.
