Being a Microsoft Office website I imagine you have a Office live account, using this sign in to office live and then go to domain management. Once you are on there, I believe there is an option to redirect your website to another page or website. Hope this helps.
Well, if you just want to redirect domain "A" to domain "B", just setup a index.html with; <script type="text/javascript"> window.location = "yourdomain.com"; </script> Maybe I misunderstood?
Redirect 301 /oldpage.html http://www.example.com/newpage.html source: http://www.webseorank.com/web-development/how-to-create-301-redirects.html
<script type="text/javascript"> window.location = "http://reddirtpaintball.com"; </script> Put that into your "index.html" on reddirtpaint(dot)com. Everytime someone types in "reddirtpaint(dot)com" into their browsers, they'll automatically be redirected to "reddirtpaintball(dot)com".
Index.html is the file that opens up when you access to that domain name... The code posted before would load that page normaly and then redirect. The best option is to do a 301 redirect as jalpari said but you need to upload a new file and support for httaccess
Changing the htaccess is the best way of doing it. Then there's no way of Google indexing a blank html page.
