Cannot sync with exchange on John's phone.
To start the troubleshooting process, I reviewed all the ActiveSync settings that were configured on John's phone and found them all to be correct. Checking the server settings and John's account, all the settings are identical to the ones configured for Steve Puls. As a test, I tried configuring the ActiveSync settings on my iPhone for the administrator account to see if I could get that working properly and I was able to. With the Administrator account working properly, I modified the settings on the iPhone for John's account and ran into problems again.
Based on these results, I tried setting up the Administrator account on John's phone and had no issues doing so which indicates the problem is not based with the phone itself, but John's account.
The problem is not related to the phone at all, as I was able to setup the firstname.lastname@example.org account on John's phone successfully.
John's account does not work properly when setup on an iPhone either which further points to an account issues. All Active Directory settings and Exchange settings have been reviewed and no discrepencies have been found when compared to another working ActiveSync user.
Testing of the settings can be performed via iPhone remotely and when settings are working successfully on a test phone, all settings are already configured on John's phone
Only John is having this issue. He has the Samsung Jack. It has Windows Mobile 6.5 Standard. All other mobile users are fine.
Also, I am seeing http status code 409 in the event application logs for his account.
We are running Win2003 SBS w/ Exchange 2003 sp2. Any help is greatly appreciated!
