Exchange 2003 Active Sync Errors 85010014 - Connect but no sync

this happened suddenly last week (after updates?) when iphone users were not able to sync anymore, followed by the windows mobile users. Here's what i have done so far:
- reinstalled iis and exchange
- reinstalled exchange sp2
- tried to recreate the \exchange-oma directory following kb817379 because form-based authentification were enabled.
- Installed a certicate from Starfield.

After all that, i'm back with the same sync problem, with or without SSL enabled.

The /exchange and /oma work.

Active sync will  make a connection to the server (authentification OK) but will hang with looking for modification.

No events in the application log.

The web site www.testexchangeconnectivity.com will give the following report:

Solved my problem! Microsoft support said it looked like a performance issue, but could not tell exactly what was happening but it it seemed to happen only with active sync.

While running the Exchange Best Practice Tool, i found 2 errors and one of them seemed related to performance. Here are the two articles i followed:

http://technet.microsoft.com/fr-ca/library/aa998162.aspx
http://technet.microsoft.com/fr-ca/library/aa998240.aspx

 I believe the 1st one solved my problem.

I still don't know why it suddenlty started to happen though.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Update: It happens only with certain mailboxes. If i make a test on www.testexchangeconnectivity.com  with a 'good' user account, it works!

If it is happening with certain accounts then the problem is probably account specific.
Ensure that the accounts have ActiveSync enabled and that the account isn't locked out, expired password etc.
Also check that the email addresses on the account have the default email address. The default email address matches your internal domain. SO if your domain is example.local and your public email address is example.com, then the user accounts should have an email address in both, but obviously the example.com would be the Reply to address.

update: the problematic accounts are OK. I made some more testing and i think there are some corrupted elements (emails/tasks/contacts/meetings) in those exchange mailboxes. It is very strange. If i empty my inbox for example and re-fill it with emails one at the time, i can identify some emails that will create the problem with activesync. Same for tasks ans contacts... I also tried to delete the entire mailbox from exchange manager and create a new one. I am able to sync until some corrupted elements are added. New emails just arrived were also identified as corrupted! Appart from activesync not working, everything else is working fine. Should i try to make a database integrity check or defrag?

MesthaCommented:
A database check doesn't always detect corrupt items, it is look at the integrity of the database itself. Corrupt items in the store is unusual, so you may have a problem elsewhere.

where should i look? I'm out of idea...

MesthaCommented:
For the cause of the corruption, the usual suspects are AV or antispam software. However I have seen storage cause similar problems as well. If the corrupt message is not causing a problem, spotting the problem could be difficult. It might even be happening outside of your server!

i'm not sure about corruption too. i'm just saying that some 'items' a causing the sync to jam. But if i put one element at the time in the sync folder and let it sync with the device, it will work, always. Sometimes i can put back 2-6 itemsat the time and it will work but sometimes not.

Can there be a problem with activesync but directpush is working? I'm not sure how those work.

How can i get a log of the sync items so i can see where it is jamming?

MesthaCommented:
There is nothing that logs to the level of per item. I have been using ActiveSync for some time and it has worked throughout that time without a single blip, so something isn't correct somewhere. Direct Push is just the transport mechanism for ActiveSync. Direct Push makes the connection for ActiveSync to operate over.
