I need assistance to provision user account. It is possible that account was created as external user and now not able to provision in Azure for SSO and receiving the following  error:

 Failed to create User in Box; Error: Box returned an error response with the HTTP status code 409. This response indicates that a user or a group already exists with the same name. This can be avoided by identifying and removing the conflicting user from Box via the Box administrative user interface, or removing the current user from the scope of provisioning either by removing their assignment to the Box application in Azure Active Directory or adding a scoping filter to exclude the user.

We already tried removing and re-adding but still getting error.
