Not getting notifications for push emails
I have an iPhone 5s with IOS 7.1.2 installed. I have a mail account set up pointing to my company's Exchange server. I will frequently not get notifications of new email until I open the email app on my phone. I won't get them when the email actually arrives in my mailbox (which is the purpose of push technology). Any ideas why I'm not getting these notifications? I have alerts turned on (banner, badge app icon, show in notification center, show preview), so ideally, I believe I have everything I need turned on. The account is also configured as 'Push' in the 'Fetch New Data' section of the menu.
Thanks in advance for any help with this.
