Can anyone tell me whether Communicator 2007 can access a users mailbox information when the only available connection is RPC over HTTPS (i.e. Outlook Anywhere)?

I've just read the articles below which would seem to suggest that MAPI is the way the connection is made, but I need to confirm. Links to articles are:
