Your customer will never see our name or branding anywhere.
No frames whatsoever - our platform was built from the ground up for white labeling.
Your customers can administer their own account, if you allow it, on a site with your domain and your HTML header and footer.
You use your domain name for services: OWA.YourDomain.com, OMA, VPN, etc.
For SSL driven items (SSL in OWA, RPC over HTTP, and ActiveSync), we can white label those as well, e.g., Exch.YourDomain.com*
