User impact: Users may be unable to load the email remediation side panel in Microsoft Defender for Office 365 Threat Explorer.

More info: As a workaround, affected users may be able to perform email remediation actions by following the steps below to the advanced hunting page instead:

Using the Microsoft Defender for Office 365 portal, go to the left navigation bar ‘Hunting’ and select the ‘Advanced Hunting’ option and select the ‘Take Action’ button. Also you could choose “Take action” from the email entity or summary panel.

Current status: Our analysis of UX logs was inconclusive in validating the root cause. However, we’ve identified that a new feature, originally intended to be introduced as part of our roadmap, may be brought forward to resolve this issue. We’re performing additional reproduction tests in our internal environments to validate the efficacy of the new feature and our next steps towards remediation.

Scope of impact: Impact is specific to some users, who are served through the affected infrastructure, attempting to load the email remediation side panel in Threat Explorer within Microsoft Defender for Office 365.
