Microsoft Edge for Business: Cross-tenant support using Intune Mobile Application Management (MAM)
Microsoft Edge for Business will support cross-tenant Intune Mobile Application Management (MAM) policies, enabling data protection on devices managed by different tenants. This opt-in feature, rolling out from February to April 2026, secures corporate data without extra enrollment or disrupting user experience. Microsoft Edge for Business now supports cross-tenant Intune Mobile Application Management (MAM) policies. This update allows organizations to apply Intune App Protection Policies to Edge work profiles even when the device is managed by another tenant. This capability helps protect corporate data in cross-tenant scenarios such as contractors, partners, or mergers, without requiring additional device enrollment or disrupting the end-user experience. This message is associated with Microsoft 365 Roadmap ID 557187. When this will happen: Public Preview (Worldwide): We will begin rolling out mid-February 2026 and expect to complete by early April 2026.
