Hi guysHappy new year!Can anyone offer any assistance?On my Windows 2003 server all of a sudden when I create a new user in Active Directory it's failing to create Exchange Mailboxs.I'l go to create a new user and it will state that it's creating an exchange mailbox and I go through the wizard. However, when I go to use Outlook on the newly created user it fails to locate it's mailbox. In the properties panel of the user no E-mail adresses have been added.Can anyone help?Many thanksMatt

Problem solved by re-building the RUS and updating now.
