I have just installed the Beta of Office 2010. It doesn't appear to be
compatable with the Office Live WEB site. It appears that there is no direct
way to save files to this service or to open them directly from the service.

I can not find any add ons to allow for this function.

It appears the only way to use this service with office 2010 is to save the
documents to the local drive and then copy them to Office Live. In turn to
open documents stored on Office Live is to save them to the local drive and
then open them with Office 2010.
