Folks, A warning. We use address book views on our 5.5 service. On occasions we have cause to rename departments (on which one set of views is based). We will select the address book view in Exchange Administrator and work through the normally trivially small number of mailboxes which need the department changed. It's always the small fledgling departments which cannot decide what they're called! Once the view is empty we delete the now redundant view. Regrettably, if you get distracted in doing this it is possible to delete a mailbox instead! Having finished renaming the department for the last mailbox in the view I overlooked to select back on the view in the left hand pane before taking the delete key. Focus was still in the now empty right hand pane, the delete key was not greyed out BUT the delete confirmation that came up was for the last mailbox to have its department changed. Of course when you're not paying full attention you carry on and select yes..... Regards, Roger Mackenzie (Glasgow University)
