How to Set Up “Mail Days to Sync” in e-mail (iPad/iPhone iOS 6)
This video is only applicable to those who have NOT updated their iPhone/iPad to iOS 7 or 7.1 Please see additional videos for iOS 7 and higher.
By default your iPad/iPhone is set up to sync 3 days of mail. This means you can only see mail you received in the last 3 days in your inbox or any of your e-mail folders. You will want to change this setting. We recommend you use the maximum setting of “1 Month” so that you can see as many messages as possible in your inbox and folders. This process will work the same on iPad and iPhone.
