You can get the free prime by going into the settings view of the app, tapping "App version" three times, and then entering the word "OZBARGAIN" in the field. Enjoy!
Will give it a go, currently I use Gmail for Calendar but Outlook for mail and that's a match made in hell.
I also use Microsoft ToDo, which is great, but Outlook insists I use Microsoft ToDo, which I do, but it won't let me connect my ToDo to Outlook because I don't have an email account on my Microsoft account, but I do have a random Hotmail account loaded for spam, and it forces me to use that.
Basically Microsoft is living up to the Magic 8 Ball "Outlook not so good".
So if I can get something that actually works, then I'm happy.
