Thanks for the info. - We'll just do this manually then over a period.
For Backup I used the backup program from the MS site pfbackup.exe which saves all the stuff easily and then can be re-loaded into the new relevant folders. http://www.mydigitallife.info/2007/1...backup-add-in/
This won't re-load directly into Outlook 2010 but you can IMPORT the .pst file created by the backup.
This gets ALL the folders including the users archived mail. I'm surprised this backup feature was never more widely publicised by MS.
