Activesync Issue with IPAD

Where would i look to isolate the cause of failure here? If in IIS logs how do I extract User specific information for a failed sync?

Thanks - SJMP

Synchronization with your iPad failed for 1 items.

Which version of Exchange are you using?  Presumably 2003?

Exchange 2007 - sorry

If this is just effecting a single user - please move their mailbox to a different store.  It will tidy up any issues associated with their mailbox / data within the store and may simply resolve the issue.

I dont have another store. But this only happened on one calendar entry.  My questions is how do I trace the root cause of this specific sync failure. IIS Logs? If so, how do I find the user, and the sync in questions.

Alan HardistyCo-OwnerCommented:
Looking at the following blog - have you installed Exchange 2007 SP2 Rollup 2 yet?  It seems to fix the problem: 
sparkisAuthor Commented:
I have SP3 on the server. The failure occurred post SP3 install.

Ah - that sounds like a new "Feature" Microsoft added.
Can you replicate the error on another iPad with the same user account?
Can you replicate the error with the same iPad with another user who was invited to the same meeting?

If I can replicate it where would I look to isolate the reason for failure.
Alan HardistyCo-OwnerCommented:
That depends on where / how you can replicate it.

If the same user on another iPad does not work, that points to the user account.  If another user on the same iPad, then that points to an iPad issue.

It was one failure last week out of thousands of successful sync's - the issue is isolated - did not repeat.

I just want to find the failure and understand why.
Alan HardistyCo-OwnerCommented:
If it is isolated, that sounds like an account / mailbox issue.

Have you tried moving the user account to another mailstore?
sparkisAuthor Commented:
Seriously - I dont have another store.

I just want to know where are the logs that would record the failure?
Alan HardistyCo-OwnerCommented:
If you have Exchange 2007, you can create up to 4 mailbox stores and 1 Public Folder store.

The logs won't tell you much, and they will be using the default website IIS logs to record what goes on.

Create a new mailstore and move the mailbox is my recommendation.

I am not going to create a mail store for one user with one failed item on active sync. I wanted to troubleshoot and identify the problem. If it is impossible to troubleshoot and gather any information from the logs, then how do people identify any activesync issues?
Alan HardistyCo-OwnerCommented:
Moving the mailbox to a new store is the equivalent of running:
eseutil /p
eseutil /d and
isinteg -s servername -fix -test alltests
The above will deal with any database corruption, but moving the mailbox to a new store is simpler and quicker, plus you don't have to take the entire mailstore offline to repair it.
Once done, you can always move the mailbox back again and delete the database.
If you are looking for an answer about what to look for in the logs - I am not the person to provide it for you, I prefer simpler methods, but that is your call.
If it doesn't work, then the logs may provide some clues (possibly).
sparkisAuthor Commented:
There is no database corruption. This is one item that failed in activesync.
