Activesync exchange 2003 with iPhone

hi, i can't retrieve  emails in folders under my inbox from iphone ( email type in iPhone is exchange) an error in IIS says:

I've emptied my inbox from outlook, and it's syncing OK, why this happens? why i should emptied my Calendar, folders under Inbox or my Sent items to sync normal?

I may be wrong but I think on an IPhone you need to manually open the sub-folder for it to sync. I don't have an IPhone but I remember someone complaining that the auto sync did not work for sub folders, they had to open the folder and then it would sync.

by: silverkornPosted on 2011-07-14 at 05:47:34ID: 36187574

By applying these hotfixes:

it updated the following components:
Davex.dll      (6.5.7655.11)
Store.exe     (6.5.7655.11)
MasSync.dll  (6.5.7655.0)

I restarted all the IIS and Exchange services but it requires a full system reboot for everything to work. Now everything works. thanks for all the help

when i went to the KB as instructed above, i couldn't find a download link for the hot fixes
can you provide me a link for the hot fixes,

I have the KB967046 hotfix available, but cannot upload it to EE as they don't allow the file type - if you drop me an email (visit my profile for details), I will email it to you, or make it available on a site you can download it from.

thank you for your reply, i applied your article until www.testexchangeconnectivity.com 
gives me the following:

Connectivity Test Successful

ExRCA is testing Exchange ActiveSync.
 	Exchange ActiveSync was tested successfully.

Open in new window

but i still can't retrieve emails under my inbox folders or Sent items, except if delete their contents, sync, then restore  some of the contents to sync with iPhone,

i still have the following error in (C:\WINDOWS\system32\LogFiles\HTTPERR)
