You can set up one way syncing from Google Calendar to your Outlook calendar. This will allow you to view items you added through the Google Calendar in your Outlook Calendar.
Tired of clicking on the navigation buttons every time you want to switch between your Inbox and Calendar? Right-click on any of the Navigation buttons and choose “Open in a New Window”, and you can keep your Calendar or Contacts open in windows of their own. They'll stay open while you deal with messages; simply use Alt-Tab to navigate between the windows.
You can set an alert to receive a "Thread Notification" when an e-mail you designate, receives a reply. These alerts can be enabled for new e-mails, replies or forwards.
When you upgraded to iOS 8, you may have noticed you receive multiple alerts for text messages. This can be changed in Settings, so that you only receive the alert for a text message once. This process shown on iPhone 6 with iOS 8, but works on iPad with iOS 8 as well.
In iOS 8 access to the “Control Center” from the lock screen, is enabled by default. This would allow anyone to disable features (i.e. Airplane Mode), without entering a passcode to unlock the device.
