Outlook 2003 error 'Could not open the item 0x80040107'

[donishere]

One user (of 15 total in our network) is experiencing issues using Cached Exchange Mode in Outlook 2003. Everytime the user tries to synchronize her Outlook folders (send/receive), the following error appears during the receive process:

Task 'Microsoft Exchange Server' reported error (0x80040107) : 'Could not open the item. Try again.'

I look in the Sync Errors folders and see that the error appears when it is "Synchronizing Hierarchy".

When I turn off Cached Exchange Mode in Outlook 2003, the error doesn't appear during the send/receive process.

The user requires that Cached Exchange Mode be turned on because that is a requirement of the Outlook's Junk E-mail Filter.

How can I get this to work?

Are you using also Exchange 2003 in a full windows 2003 environment ?
My expirience is when you are in mixed mode, the Outlook 2003 Cashed Mode doesn't work.
