Why wont my Samsung tablet sync my mail accounts?

Tab S2 won't sync my Google Mail, Google Calendar or Google Contacts. I have checked the settings on the S2 and on my Google account, done a restart, disabled my Gmail and then enabled it again. No change.

Hi Just a thought for your Calendar sync problem:

open the menu and at the top is Calendars, click on that, select your google calendar and de-select My calendar and see if it syncs
