The Android system allows you to operate and sync your emails, contacts, calendars and other items using multiple accounts. You can set your accounts to sync these items on your device with the servers automatically or manually.
Run the Settings app, select 'Accounts & sync' under PERSONAL.
At the top, tap to switch the 'Accounts & sync' to 'ON' for automatic syncing, or 'OFF' for manual syncing.
When the 'Accounts & sync' is switched off, you can touch an account and sync contacts or other items manually—either touch an item to sync or tap the Menu button then 'Sync now' to sync all items. The last synced date and time are shown below each item.
