Greetings Experts - first of all, apologies if I have posted this question into the wrong board. I have a Windows Server 2003 Active Directory Domain (Domain Controllers are all on Service Pack 1) with Exchange Server 2003 on Service Pack 2.
I am using ADModify.Net to add entries to the 'Accept Messages from everyone except' Delivery Restriction under the 'Exchange General' tab of all of our mail-enabled Active Directory accounts. To do this, I am using the 'unAuthorig' attribute in the Custom tab of ADModify.Net along with the 'Multivalued Append' tick box (as I want to add a number of entries for our AD accounts to not accept e-mails from). Seems to work fine.
I am at the testing stage at the moment, and want to have some way of reversing such a large alteration to so many Active Directory accounts if the firm decides it does not want this AFTER it has been put in (we are talking about 1000 mail-enabled AD accounts and so I don't want to have manually change each AD account!)
My question is: does anyone know the name of the attribute I would use to reset each mail-enabled AD account back to 'Accept Messages from Everyone' under the Delivery Restrictions area of the Exchange General tab?
ADModify.Net does not provide an area within the GUI for doing this (or at least version 184.108.40.20667 doesn't). So I have to use the CUSTOM tab to do this - but this requires you to know what the actual attribute name is for the change you want to make.
I have looked reasonably hard on the internet and cannot find the attribute name I need. Failing this, is there any other bulk way to remove the change I have put in using ADModify.Net from each mail-enabled AD account?
Any help appreciated - 250 points are available!
