What is the cause of lpAdviseSink not able to retrieve message and have "The client operation failed" error? RRS feed

  • Question

  • I use messagestore Advise to register a callback for new email message event. When the callback is call, I use OpenEntry() to get message detail.  However sometimes, after it has been running without problems, OpenEntry() starts to return error, "The client operation failed", and MAPIError->ulLowLevelError is 0.  I can still ping the session and send emails.  The only way for the new message callback to work is to Unadvise() and Advise() again.  So what was the cause of the problem?
