I've updated my clients (Office Communicator, Live Meeting client, Live Meeting/Office addin pack) to the release candidates, but I haven't upgraded my server infrastucture from the public beta to release candidate yet.
I'm now having problems scheduling a Live Meeting through Outlook. I can create an ad hoc Live Meeting using Office Communicator, but through Outlook or the Live Meeting client (meet now) I can't. It throws the same error that you see if you haven't setup the user account in the Conferencing addin properly, but I have and when I test the connection it always succeeds. I've specified the server and test the connection successfully and used auto-configuration and click test connection and it's always successful, but then scheduling a conference causes the error.
Has anyone else had this problem, or is anyone successfully using the Releace Candidate clients for Live Meeting and Live Meeting addin pack with the public beta servers?
