Outlook pst went over limit of 2 GB

Hi there, I have a user who has gone over the limit of 2GB with his .pst file. Anna told me before that MS has a tool that can recover it. I’ve used the tool and done the scanpst.exe after that and could open the new pst folder but now it just have loads of recovered folders and I can’t get the address book and calendar back. There is folder with this in, but there’s no email addresses etc in. Is there an easy way just to get the addressbook and the calendar back from the damage outlook.pst???? Pleaaaaase help!!! This is my MD’s calendar that he needs to get back! Many thanks!
