Dear customer: In order to better troubleshoot the issue, please help collect the following information: 1. Open ESM on Exchange server, open registry editor, 2. Navigate to the following registry: HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeAL\LDAP Operations Right click LDAP Operations, select modify, input 7 under value data. 3. Open Event Viewer, navigate to Application, right click Application, and select clear all events. 4.
