I have a user with an Outlook 2003 PST that has reached the maximum size of 20 gigs. Fun Fun! The file will not open and display properly in Outlook at this point. It throws a message stating that the file has reached maximum size, this is displayed in the pane where the inbox items are usually listed. I had trouble finding info on a truncation utility that is specifically stated to handle the newer 03 style databases. So for starters, I ran scanpst on the file, errors were found, so I hit repair. The utility ran for hours and finally completed. The database is still unreadable. I've fixed plenty of older databases by running pst2gb to truncate then running scanpst. I tried running pst2gb on the database but it throws a run-time 52 error when I select the broken database. I can only assume that pst2gb is not designed to work on the new and larger db. I don't know what to do next. Is there a cropping utility for the 2003 style databases that have reached max size, or some other utility or method I missed?
