A synchronization error indicates that an action or event cannot be completed or run because the data it requires is not present or valid.
What To Do
To resolve these issues you need to find the core issue which requires finding the first error in the sequence and identifying the cause of that - the error shown above is too late in the chain of events to know what caused it.
Therefore work back through the SUM trace logs and locate the first error. If you need to contact us please run the Sophos Diagnostic Utility of the SUM server first, attach the output file and quote this article.
