N/A86000209The error code has to do with the sync key of the folder hierarchy. When you sync a number is exchanged between the device and data end. If you make say 10 changes between 10 different sync's than the device will send 10 back. What is happening is the device is sending back a number that is way off, say 4.The most common cause of this is resetting the device without adequately flushing the flash file system's RAM cache.
To avoid this in the future, press the suspend button before resetting the device. When the device goes into hibernate mode the cache is flushed. (you may want to wait a few seconds after hitting the button to allow the cache to be written).
With the smartphone, always turn off the phone, and never yank the battery. The ram cache is flushed to flash during the power off process.
Try unselecting mail for sync. Then re-enabling it.

N/A80072F0DThe security certificate on the server is invalid. Contact your Exchange Server administrator or ISP to install a valid certificate on the server.This issue occurs because an intermediate certification authority (CA) certificate is not present on the device or on the Exchange Server server with which you are synchronizing.
Windows Mobile-based devices do not generally contain intermediate CA certificates in their certificate store. Internet Information Services (IIS) will send the whole certificate chain to the device. However, IIS will do this only if it can verify the whole chain. By default, the device does not contain these certificates. Therefore, the server must send them. The device must contain only the root certificate in its certificate store.
Frequently, this issue occurs with GoDaddy certificates because either the root CA certificate or the intermediate CA certificate is missing from the certificate store on the server that is running Windows Server 2003.
Frequently, this issue occurs with VeriSign certificates because the intermediate CA certificate in the certificate store on the Windows Server 2003 server is expired.

Notes:
Originally based on the information provided at Exchange Error Codes. Used with permission.

Errors received after a synchronization attempt on the device have error codes appended to them. These codes help determine the source of the error. The errors are one of the following types:  

Error code Descirption
DEV_errorcode This error code indicates that the error was from the Server ActiveSync client on the device.
MIS_errorcode This error code indicates that the error was from the Mobile Information Server with the Server ActiveSync component installed
SYNC_errorcode This error code indicates that the error was from the Exchange 2003 server. MIS_errorcode errors were replaced with SYNC_errorcode errors on Windows Mobile 2003-based devices.
HTTP_errorcode  Standard HTTP error (Internet related)
CONNMGR_errorcode Connection Manager error
INTERNET_errorcode Standard WinInet error (Internet related)
HEX errorcode  

These errors can appear either on the device, the Application Event Log, IIS Logs or the NexTags logs.
