My iPhone and iPad are connected to my Exchange server, and right after an e-mail is sent, both of them light up and receive it.
I also run Outlook 2010 (connected to the same Exchange server), and starting a few days ago it stopped receiving e-mail right after it is sent. Sometimes it will come in 10 minutes late, other times, it won't come in until I restart Outlook. All the e-mail will come in when I restart Outlook.
Any thoughts on what's going on?
Update 1: Here's an image of my connection status:
