Appointment Requests From Office Live Into Default Outlook Calendar?

I use MS Office Live Small Business for my website and email. I use Outlook to manage my email on my computer, connecting to Office Live with Outlook Connector. Till now, I have not used the online Office Live calendar, I've simply used the default Outlook calendar on my computer. Today, though, I received a meeting request from a client. I "accepted" the meeting and checked in my calendar to make sure it had recorded it, but could not see it. I eventually found it in my online Office Live calendar.So now I have two active calendars, which I don't want. Can I tell Office Live to record appointments to my Outlook default calendar? Or would I be better off switching to the online Office Live calendar? If I do the latter, is there a quick and easy (!) way to transfer all my appointments from my default Outlook calendar to the online version?(One reason for wanting to use only one calendar is that my HTC smartphone will only sync to one calendar, so it doesn't pick up any appointments on any other calendar.)
