Thank you for your post!
The Identities
property of a user within Azure AD indicates that user’s primary identity provider. You're correct when it comes to the ExternalAzureAD Identity - an internal user invited an external user to your Azure AD tenant as part of the B2B collaboration feature, which is a capability of Azure AD External Identities that lets you collaborate with users and partners outside of your organization. For more info - Properties of an Azure Active Directory B2B collaboration user.
After invitation redemption
After the B2B collaboration user accepts the invitation, the Identities property is updated based on the user’s identity provider.
- If the B2B collaboration user is using a Microsoft account or credentials from another external identity provider, Identities reflects the identity provider, for example
Microsoft Account
,google.com
, orfacebook.com
. - If the B2B collaboration user is using credentials from another Azure AD organization, Identities is
External Azure AD
.
Additional Link:
Configure external collaboration settings - This lets you specify who can invite external users, allow or block specific domains, and restrict what external guest users can see.
I hope this helps!
