Microsoft has released a bunch of tools or utilities for integrating with or migrating to their online services, e.g. BPOS (Business Productivity Online Suite):
- Sign-In: A client application to allow a user to access the services such as SharePoint, LiveMeeting or Online Mail. it can also configure your Outlook (if it’s the same as the trial edition I’ve used).
- Migration Tools for Exchange (x86 and x64): Migrate users to the hosted Exchange service.
- Active Directory Integration: Integrate your corporate AD with the hosted service for a branch office!
