When you open the app you will be asked to login the first time. After logging in you will be brought to the mobile webpage of the hotmail.com mobile site. Please also note you do not actually leave the app when doing this you still are within the Hotmail for Android app itself. Once the mobile site has loaded you will be able to read, compose, save, and perform any other activities the same as you would if you were accessing the mobile site within your browser. While it is not the best of both worlds and an Android specific app may give you some other features this app does a pretty good job at everything it should.
Overall, this is app is great for what it does. I would say cautionary thumbs up; the addition of push notification when new mail has arrived would be great and would give it full thumbs up. Needs some work! At the time of this review the Android Hotmail Android App is free.
