Just attached Windows Live Domain to my .com here.
So far pretty interesting in that now with the help of the Outlook.com app on my Android phone I’ve regained the ability to sync between my phone and desktop.
I honestly looked into this after Google and MS had a spat apparently and now they barely talk to each other (lost my calendar sync!).
Now not only do I have my calendar again, but now I get all sorts of cool sub domains to attach Live services to my main domain!
It also kicks Google Apps in the shins since it’s still free, supports more users, and apparently provides the same services.
And to top it off, my webmail interface kicks directly to Outlook.com, very nice.
