Explanation
This Warning event indicates that a Lightweight Directory Access Protocol (LDAP) notification created by an Exchange component has failed. In the absence of other events, this usually means that there is a problem with a specific user or operation. Therefore, this event should not affect overall mail flow. However, certain Exchange operations that depended on the failed notification can fail. You should investigate the cause of this event.
User Action
