I have something new to add in regards to this specific issue. I have 4 iPhones here. All of them are pre-3G running FW 2.0 We have Exchange Server 2003 and
two our of the
four phones
will accept an Exchange account and actually sync.
One of the phones (even after being wiped with a fresh FW 2.0 update) will
not allow any exchange account to successfully work, including my own account which works fine on my iPhone and that users email account configured on my phone works correctly. If that user makes an attempt to authenticate for the first time from his phone, it locks out his account immediately. The second iPhone user cannot get his iphone to work with Exchange either, but it does not seem to lock out his account. Just tries to update forever.
I have checked everything from Exchange configuration server side to password lengths and FQDN's for the exchange server address.
My theory is that there might actually be something phone centric that is preventing an Exchange connection. Why would 2 of the 4 phones work? All of them on the same version of iPhone software. All 8 gb and all using Edge from the same building on the same exchange server all with similar type exchange accounts.
One other thing to mention is that 3 of the 4 iPhone users were configured with Synchronica services (
http://www.synchronica.com/products/syncml-gateway-for-businesses.html ) before the update. All three of them have gone in and deleted their accounts with Synchronica. 2 of those users are suffering the reported symptom.
If anyone else is having this problem and reads this, please post your info. I'd be curious if anyone with an exchange server has only select phones that do not work.
