Folks, quick walkthrough on the new MTO feature that landed. You can now set up relationships between your tenants and manage sync from a single place if access is granted by the member tenants.
Once set-up the benefits include:
🎯 In Microsoft Entra you will be able to differentiate in-organization (MTO) users vs out-of-organization (B2B/Guest) external users
🎯 Improved collaborative experience in the new Microsoft Teams client where switching is more seamless and faster! https://techcommunity.microsoft.com/t5/microsoft-teams-blog/microsoft-teams-advantages-of-the-new-architecture/ba-p/3775704
🎯 Improved people search experience across tenants and viewing the profile cards of users from other tenants.

PS Your tenant needs to be enabled for Targeted Release to try out this preview. You can enable this in M365 admin center > Settings > Org Setting > Organization profile tab > Release preferences > Targeted release for everyone
