Synchronization Error 85010014
Error 85010014 is often less to do with syncing and more to do with the devices at either end - namely your Windows Mobile phone and your Windows XP PC.
These are the reasons and explanations for Synchronization Error 85010014:
1. Application Data Folder is Redirected - on your PC, your Application Data folder (commonly found in C:\Documents and Settings\[USERNAME]\Application Data) is redirected to an external source, probably due to your Outlook configuration
2. Outlook is in Offline Mode - this is largely a connectivity error, and can occur when Outlook is in Offline mode (resolved by going to File > Connect to...) or when Outlook fails to connect to the Exchange Server. Microsoft Outlook should always be in Online mode when synchronising.
3. Outlook script blocking - this is usually down to security applications either at a local level on your PC or if part of a corporate LAN, at a domain level. Check your security application online help to check how to disable script blocking for Microsoft Outlook. This shouldn't occur for any home user.
4. ActiveSync is registered incorrectly with Outlook - this can often be resolved by installing Microsoft ActiveSync 4.5 - however running a repair installation (which requires the Microsoft Office CD ROM) may also work, as may deleting the relationship in ActiveSync (File > Delete Mobile Device).
