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 particular 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.

To review the current MSExchangeADAccess service diagnostic logging settings, in the Exchange Management Shell, type Get-EventLogLevel MSExchangeADAccess.
To change the logging level for the Topology category, in the Exchange Management Shell, type Set-EventlogLevel MSExchangeADAccess\Topology -Level Minimum.
