I am trying to create a Global Event sink with the help of SystemMailbox. I could do this using regevent script in 2003.Looks like things have changed in 2007 with the power shell scripting.Firstly, I don't see any such account under the Active Directory users. Can anyone tell me if there is any such concept (similar to 2003) here?I assigned my Administrator account full privileges using this command -Add-MailboxPermission -user Administrator -accessright fullaccess -inheritanceType all. However, I need to do this for the service account.Any help and or links will greatly be appreciated.Thanks in advance,Raja
