I have a client who is running 4 iphone 3GS handsets all setup to use activesync for exchange. They are having a problem where contacts are not being synced at all and the calandar and emails will only sync if Outlook is open on their laptops. The iphone is not connected to the laptop when this happens.
I have entered one of the users details into my HTC Tattoo phone and his emails and calandar sync fine but the contacts do not. I have tried the following web site:
The first activesync test completes with no errors when using the same users credentials as above.
Going through the event logs I find two errors messages relating to activesync which are given in the text file attachment. The first error relates to knowledgebase article 905013 which talks about HTTPS timeouts on the firewall. I am using a Draytek Vigor 2820n router and have increased the timeouts to the 59 minutes recommended by apple.
This all used to work ok before Christmas. The only things I have done since is run a Microsoft update to make sure the server is fully patched, and Backup Exec 12.5 is also on SP3 with the latest hotfixes (through Liveupdate).
The server is Windows Server 2003 SBS and Exchange 2003 SP2.
Any help welcome as with the snow I am short staffed today.
