When using MS Exchange 2013 and the CA Data Protection Exchange Server Agent (ESA), the event log will produce the following benign error:
Event id: 1057 MSExchange Extensibility Agent 'CA DataMinder Exchange Server Agent' went async but did not call Resume on the new thread, while handling event 'OnSubmittedMessage'
Microsoft introduced a code change in Exchange 2013 which produces benign errors in the event logs when the Data Protection Exchange Server Agent is also present.
After applying FIX:RO88793 (incorporating Integration_x64_14.5_HF0189) the thread is initialized for asynchronous event handling and the error no longer appears.
FIX:RO88793 is available to download from the CA Support Portal (http://support.ca.com)
The error is benign in respect of the code change within MS Exchange 2013.
The fix was created as per Microsoft's recommendation referenced in the link below;
