Exchange won't push to iPhone
Posted on 2012-09-04
I have an iPhone 3GS and Exchange Server 2003. Until recently, my Exchange server used to push email to my iPhone and I would receive email immediately it arrived. Some weeks ago I noticed that my iPhone battery would drain itself in a matter of hours and I eventually found the cause to be email. When I turned off Push on the iPhone the battery life returned to normal but I now have to check for mail manually.
With Push set to on and viewing the email on the iPhone, the phone repeatedly checks for new mail about every second which drains the battery. The iPhone settings say that if Push is not available then it will default back to Fetch which I guess is what is happening which leads me to believe that it's Exchange that's causing the problem rather than the phone.
Can anyone suggest why Exchange should now be unable to push email please?
