Azure B2B Integration with SharePoint Online and OneDrive is now generally available.

This message is associated with Microsoft 365 Roadmap ID 81955

When this will happen

Microsoft will begin rolling this out in late July (previously late May) and expect to complete rollout in late August (previously mid-June).

How this will affect your organization

To enable this integration while it was in Preview, customers were required to enable the feature in SharePoint Online Management Shell and to enable One Time Passcode in Azure Active Directory (AAD). Going forward, only the PowerShell flag is required to enable this integration. While disabled, external sharing in OneDrive and SharePoint Online will use the SharePoint Online One Time Passcode experience.

  • When the integration flag is enabled: External users will be invited via the Azure B2B platform when sharing from SPO. If Azure B2B One Time Passcode option is enabled, recipients that do not have password backed accounts will get a sign in experience through AAD that uses One Time Passcodes. Otherwise, external users will authenticate via their own AAD account or via an MSA account.
  • When the integration flag is not enabled: External users will continue to use their existing accounts previously invited to the tenant. Any sharing to new external users may result in either AAD backed accounts or SPO only email authorized guests that use an SPO One Time Passcode experience for sign in.

Note: This integration is still disabled by default and can be enabled by tenant administrators using the SharePoint Online Management Shell.

What you need to do to prepare

You might want to notify your users about this new capability and update your training and documentation as appropriate.
