I have the same problem that was dealt with in this solution 22080763, I've tried to drill down using the ADSI tool but get the same error as the user in the problem referenced above. However, when I try to run the script outlined in the accepted solution I keep getting an error. Here is the command I'm typing in exactly -
(For reference the server name is hdmailserver, domain name is hooperdolan.ie)
dsacls CN=MailboxStoreHDMAILSERVER,CN=FirstStorageGroup,CN=InformationStore,CN=HDMAILSERVER,CN=Servers,CN=FirstAdministrativeGroup,CN=AdministrativeGroups,CN=MicrosoftExchange,CN=Services,CN=Configuration,DC=hooperdolan,DC=ie /P:N
The system cannot find the file specified.
The command failed to complete successfully.
