On Google based tablets you have to activate your calendar and contacts. If you do not have a company exchange account first sign up for a Google gmail account. When you first open your tablet and the calendar you will be ask for this info. Use your gmail user name and password. in the server line use m.google.com. If you miss this step like I did you can go into settings-accounts and sync- add account (bottom of page)-corporate. Follow instructions and put the m.google.com on server line. Bingo, you are on. Took me hours and hours (two weeks) to find this info.
