Yesterday, when i checked exchange problem at my customer i got microsft exchange security group like Organization Management, Recipient Management, etc. is missing in Active Directory.
This article will explain how to recreate microsoft exchange security group.
Now Running Setup.com /preparead won’t allow you to recreate it as OtherWellKnownObjects attribute on the Microsoft Exchange Container will be pointing to Deleted Objects , It has to be Removed
i cannot remove attribute via adsi edit
then i try to remove via LDP
type windows+R type LDP
Click Connection then connect, Click Ok if you running on the Server itself
Choose > Configuration Container
Now You won’t be Expand it . Unless you Bind it
Connection –> Bind
Double Click on Configuration > To Expand
Scroll down to Microsoft Exchange Container > Right Click > Modify
Now we got to Edit OtherWellKnownObject attribute
Attribute : OtherWellKnownObject
Choose : Replace
Click on Enter
Now Empty Value has been Added, Click Run
Now you could see in ADSI Edit Other Well known Objects have been Cleared
Now Setup.com /preparead is successful
and now microsoft exchange security group are back
Note : you need to assign access to user account exchange administrator and computer exchange server like “exchange trusted subsystem” “Exchange Servers” “organizatoin management”and others.
