B2B Collaboration Setup

Security add-in for Microsoft 365

The Azure Enterprise Application for DKE is configured as a multi-tenant app.
This allows Microsoft tenants outside your own organization to be added using the DKE App Wizard under “Azure Domain Names.”
The main configuration for B2B collaboration takes place in Microsoft Entra and Microsoft Purview.

Key Requirements:

• Guest users (identified by #EXT# in their username) require an E5 license and access to shared Sensitivity Labels.
• For cross-tenant collaboration, both organizations must:
  • Set up External Identities
  • Enable Cross-Tenant Access

Resources:

• Implement DKE B2B Scenarios
• Manage Cross-Tenant Access Settings for B2B Collaboration
