I have about 20 e-mail user accounts set up with our domain pointing to the zoho e-mail now.  The e-mail help documentation indicates that e-mail user accounts should be automatically appearing in the Organization contacts and auto-filling when a user types another user's name or e-mail address in an e-mail message or @Name style for streams.  Neither are happening and I cannot seem to figure out what I am missing to make users easy to find each other.  Will you please review and let me know what I need to do so we can begin using streams and Organization wide contacts based on the users in the domain?  Thanks much!
