One of our clients have multiple iPhones connecting to their SBS2003 server and I have the phones setup fine, they connect but not all emails are synced. For example I am logging into OWA and can see 10 new emails for today but only 1 of those is showing on the iphone. Missing emails are both internal and external. I have removed and readded the account on the iphone, rebooted the server multiple times with no change.
In the servers application logs I can see DAVEX MSExchangeActiveSyncNotify
and Server Activesync all processing normally with no errors.
I have recently reinstalled Exchange and everything else on the server is working without issue. I have rerun the CEICW multiple times and checked all the IIS settings as per http://support.microsoft.com/?kbid=817379
to no avail.
I have come across many exchange/activesync issues but never any that I can't find any errors for? Any ideas what I can check next?
