Microsoft last week revealed Office 15 on ARM. The company also showed that Google’s services work with Windows 8 Consumer Preview. Just like on Windows Phone, adding a new account gives you the opportunity to set up your Gmail account and pull in mail and calendar appointments from there.
Microsoft is adding in these services by default, rather than just ignoring them and integrating Hotmail/Exchange by default. No more detail was given, but you’ll be able to add multiple Gmail accounts, subscribe to multiple calendars from one account and that there will be threaded email messaging.
