My wife fails to sync her 8525 with her laptop. The last time that she synced was 7/22/08. Now when she tries to sync she get an error "There has been a change made on your server that requires you to re-synchoronize all item on your device. You may lose changes made since yor last successful synchronization". There is a support code : 0x8600050D.

Her laptop is vista so she is obviously using WMDC & obviously it can connect. What I don't understand is what server is being referred to? She doesn't use an exchange server or anything like that. Any suggestions would be helpfull.
