I configured my Android phone to get my Nmail without any problems. I also have a personal Gmail account. What I cannot see is my Nmail
I was able to see my Outlook calendar using the old system.
using your calendar app, you will need to add in your neiu email account. There are a couple of different ways to achieve this and I've added a couple of links that should help you.
of course the easiest way is to use the gmail app available for the android which will automatically configure your calendar access for you when the app is installed.
Once it is configured, you can switch back and forth between calendars using the three little boxes in the upper right corner of your calendar (when using your android phone).
