Microsoft Defender for Office 365

Email & Cloud Security

The Microsoft Defender for Office 365 adapter pulls email threat assessments, safe attachment findings, and phishing detection data into Clariti for unified email security visibility across your Microsoft 365 environment.

What Clariti Collects

What You'll Need

  • Global Administrator or Application Administrator role in Microsoft Entra ID
  • A Microsoft 365 E5 or Defender for Office 365 P1/P2 license
  • ~5 minutes to complete setup
  • Your Clariti account with adapter management permissions

Get Your Credentials

If you have already set up the Microsoft Entra ID adapter, you can reuse the same app registration — just add the additional API permissions listed below and re-grant admin consent. See the Microsoft Entra ID guide for the full app registration walkthrough.

In the Azure portal, go to App registrations and select your Clariti app. Under API permissions > Add a permission > Microsoft Graph, add this Application permission:

  • ThreatAssessment.Read.All

Click Grant admin consent for your tenant. Copy the Application (client) ID, Directory (tenant) ID, and a valid Client secret value.

Enter Credentials in Clariti

Verify Connection

Click Test Connection in Clariti. A successful connection returns a green checkmark. The first data sync typically completes within a few minutes.

Troubleshooting

  • 401 Unauthorized — The client secret may have expired. Generate a new secret in Azure and update it in Clariti.
  • 403 Forbidden — Ensure admin consent was granted for ThreatAssessment.Read.All and that a Defender for Office 365 license is active.
  • Timeout — Threat assessment data volumes can be large in active tenants. Clariti retries automatically.
