Azure B2B SharePoint Integration

Frequent Visitor

I've followed the steps outlined here for enabling Azure B2B integration with SharePoint & OneDrive: Azure AD B2B integration for SharePoint & OneDrive - SharePoint in Microsoft 365 | Microsoft Docs


It has enabled successfully however there appears to be no difference when sharing from SharePoint and users aren't being added as Guests in Azure AD.


Other steps I've tried:


1. Enable OTP in External Identities

2. Create User flow in External Identities to allow Azure sign up and OTP. 


Has anyone else had luck configuring this that can provide any futher guidance? Thanks.

@MartinN265 Hello,

Get-SPOTenant | Select *B2B* If the cmdlet returns a value 'true', the integration is successful.

Make sure you are inviting people who are already not in your directory. Also, try configuring a conditional access policy such as MFA so that the next time you share an item in SharePoint or OneDrive(after enabling the integration) with an external user, the recipients are enforced to authenticate via MFA before accessing the content.

For more information, please check out the following blog. 



@MartinN265 SPO will no longer rely on the legacy SharePoint Invitation Manager. Microsoft has updated the site sharing experience to use Azure B2B Invitation manager instead of SharePoint Invitation manager. Thus, this change streamlines the process of inviting external users to access resources more efficiently. Find more information at
