I created a WIndows Live account some years ago and chose @live.com as the domain.

Since then I've noticed the address is displayed differently across Microsoft products and services. Some show it as abc@live.com, others abc@LIVE.COM. Windows Azure for instance shows it as *** Email address is removed for privacy ***.

I know this is purely aesthetics, it makes no difference to the functionality, but is there something amiss?

When reviewing accounts at https://account.live.com/summarypage.aspx, the address is shown in lower case. Other aliases though are shown with the domain in upper case - @LIVE.COM.
