B2B invitation status
Azure Active Directory B2B account.
Now there isn't possiblity to generate report, if B2B user has activated account or not. It would be good to have feature to list not activated users from administrative perspective. Example when doing acocunt clean up.
There are fields in profile like Source which contain Invited user or Resend invitation button is visible. Those indicates if user hasn't activated invitation.
Or even have automatic removal on directory, if invitation hasn't been approved within X days, B2B account is removed automatically. As if account hasn't been activated, it cannot be used anywhere.
