Well, first off, you have MSN on your site, Second, you are offering it up for sale. Third, it is only a parking page.
So far, it sounds like you have no interest in the domain and have done nothing to show you have rights to the domain. So this begs to ask, why did you register this domain? I would easily assume it is to steal traffic menat for Microsoft. Though MSFT is not a TM, MS can show that this is how thier company is identified in the financial world and argue you registered the domain only to steal traffic.
You can make up any story or have plausible explainantion to make yourself feel better, but just by your posting, we all know it was registered in bad faith. This is how is could possibly be conceived if challenged.
