Exchange Server Root / Child Domain architecture administrative tip

Some of the Organization have Microsoft Exchange Servers implemented into Root Domain and active users are created at child domain, some times created administrative challenges where Exchange administrators couldn’t be able to pull out the child domain users with following error.

“The requested search root domain.local/Users’ is not within the scope of this operation. Cannot perform searches outside the scope ‘child.domain.local'”.

Ran the following Powershell commad to change the scope so administrators can view the entire domains.

  • 2007 = $AdminSessionADSettings.ViewEntireForest = $true
  • 2010 / 2013 = Set-AdServerSettings -ViewEntireForest $True
  • or use –ignonreDefaultScope on the command if applicable, i.e. get-mailbox –ignonreDefaultScope
