Event Viewer logs are not showing who(user name) changed mailbox permission in a exchange server.
I was logged in as "administrator" and tried setting a mailbox permission for a User mailbox. Once after successfully setting the mailbox permission, i checked the Event viewer log in Domain Controller machine to find the user account name which tried to set the permission on that mailbox.
But Event Viewer shows the User as "User:Domain\MailboxServer$", instead of showing the exact account name which was logged and which did the change on that mailbox (instead of "User: Domain\administrator)..
This happens in Exchange Server 2003/2007/2010....
Any reasons why the event viewer has not recorded the user name that was logged in.
