The File in Use error while splitting a PST file usually occurs because Outlook or another application is accessing the PST at the same time. To fix this problem with solutions like DataVare Outlook PST Split Expert, make sure Outlook is entirely stopped and that no additional applications are locking the PST in the background. You can use Task Manager to check this and stop any OUTLOOK.EXE processes that are still running. Next check to see if Outlook has the PST set as the default transfer destination. This could keep it in use. If the PST is on a network the drive, make a copy of it on your computer before you divide it. After making sure the file is free use the PST splitter tool again and continue with the split. This makes sure that only the tool can access the file which stops the File in Use problem and lets the splitting happen smoothly without losing any data.
