MC256838 – Updated November 02, 2021: Microsoft has updated the rollout timeline below. Thank you for your patience.
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 mid-January (previously late July) and expect to complete rollout in mid-February (previously late November).
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.
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.
