Question
I enabled domain-mapping to an organization, but the users with that email domain were not added to the organization. Why doesn't the mapping work?
Answer
For an existing user to be automatically added to an organization when adding a domain mapping, they must have a verified email address. This occurs when an end-user completes the verification process by following the link in the verification email sent from Zendesk. Any existing users with unverified email addresses will not be automatically added by domain mapping.
