If I understand you correctly, you want to link your Microsoft account ("MA" for short because I'm lazy) to your new account, sbwa. You started sbwa with your Facebook account. Steps: 1. Log onto your old account and link some other account to it (make a new dummy Gmail account for example). 2. Log off, and log onto your old account [b]again[/b], this time using your dummy account. 3. Unlink your MA. 4. Log into your sbwa user via Facebook authentication. 5. Link your MA.
