Changing User Email Address in Microsoft Entra External ID

I'm looking for a way to update the email address of a user in Microsoft Entra External ID in my external tenant that registered with Email/Password.

I came across documentation for resetting redemption status for a guest user, but this does not apply to external tenants.

Is there a way to update the email address (issuerAssignedId) for a user after initial creation in Entra External ID?

Solution

  • External ID uses the same Graph API commands as B2C.

    You can update the identity.

    "Updating the identities property requires the User.ManageIdentities.All permission. Also, adding a B2C local account to an existing user object is not allowed, unless the user object already contains a local account identity".

    Note that the existing Identity has to contain a local account and you have to update the whole Identity array.

    Since you are changing the user Identity, they will not be able to login with their previous one.
