Azure AD B2B collaboration

One of the new things in the Azure Active Directory (AD) identity space is Business to Business collaborations, and adds to your Azure AD. Azure AD has excellent SaaS application integration. In this post, find out how you can provide access to those applications to external B2B partners.

Here’s how Azure AD B2B works

Use Cases

Azure B2B is great for providing external partners with access to your organizations cloud applications and resources.

Get Ready…..Build your CSV

Your CSV must be less than 2,000 rows, but you can upload multiple CSVs

Uploading and sending invites

In the azure portal you’ll want to navigate to your Azure AD where these user objects will reside and require application access. Click add user and choose Users in partner companies from the type of user drop down. Browse for the CSV and you’re off!


Once uploaded the users in the CSV will receive an email like this:

and then be directed to an account claim page:

They will then be sent to the My Apps portal where they can access the applications they were granted access.


  • Multi-factor authentication (MFA) not supported on external users.
  • Invites are possible only via CSV; individual invites and API access are not supported.

  • External user access to on-premises applications not tested.
  • External users are not automatically cleaned up when the actual user is deleted from their directory.
