Like github.io, heroku, they allow you to host content in their subdomain like xxx.github.io, yyyy.heroku.com.
I am wondering can is it possible for me as a global admin of office 365 to host html website at subdomain of Microsoft assets like
*.microsoftonline.com *.office365.com *.microsoft.com ?
So for example, I can host my application on xxx.microsoftonline.com.
Is it possible for you to set cname or A record of xxx.microsoftonline.com to your own domain or ip address?
Or you can edit html file in such subdomain?
Do Microsoft provide such functionality?
