Office 365's public-facing website is part of SharePoint Online. It comes with an online design tool and a set of plugin components to simplify building a basic business website. The bundled templates offer a guide to good content, and there's also scope for editing site CSS for a more customised experience.
Microsoft's Lync unified communications tool is relegated to giving Office 365 IM, presence and collaboration features. That's enough for most small businesses, and the built-in management tools speed up deployment.
Much of Office 365's beta support is handled through a community site that brings together support forums, the Office 365 blog and a set of information wikis. It's a step above the usual beta non-support, with engaged and responsive Microsoft staff and a growing community of service users.
