Intermittent Connectivity Problems with Exchange 2003 and Smart Phones

I have a problem with a particular exchange 2003 server. I have two smart phones that are connected up to it...

Nokia E63 that is accessing the server through Mail for Exchange
iPhone that is accessing through the standard Exchange mail account settings

Both phones work fine for a while when hooked up to exchange, but after a week or two, the iPhone intermittently connects, and the Nokia seems to corrupt its mail for exchange. It is possible that both phones are damaged in some way, but in my oppinion, highly unlikely.

I was wondering if anyone has had similar problems, or if anyone has any ideas to further diagnose this issue.

If the above hotfix doesn't work then refer to this article:

We have installed the hotfix, but the iPhone still has the "Cannot get mail... connection to the server failed" message. So I am going to work through the article and will let you know how it goes.

Make sure you have HTTP Keep Alives on and set to at least 120 seconds.

Does the iPhone have full signal? You can test activeSync from www.testexchangeconnectivity.com
