These details are definitely correct; I used them to do the Active Directory export. What am I missing?
You can expose the security page on Exchange Server through the registry modification called ShowSecurityPage as shown in Figure A.
Once you add this under HKEY_CURRENT_USERSoftwareMicrosoftExchangeExadmin and then right-click on Properties in Exchange System Manager (ESM), you will see the screen shown in Figure B.
In Figure B, note that I do not have Deny ticked on the 'Send As' and 'Receive As' permissions for the administrative account.
Double check that your service account is a member of a group that has more restrictive rights as it relates to 'Send As' and 'Receive As' rights.
You'll also want to confirm that you typed in the appropriate port as well: port 389 or 390, depending on the implementation of the Active Directory Connector (ADC). You can use a Windows Support utility called LDP.EXE to attempt to connect to the target organization to see if you are getting similar errors.
