After encountering numerous problems with my Outlook 2010 files (.pst),, I discovered that Outlook files should be less than 2 gigabytes. I have numerous PST files that are far larger than 2 gigibytes. Is there a way to split the files? when I try to open them in Outlook, i get an error message informing me that the file contains errors. I attempt to fix the files with scanpst but have not been successful. I would appreciate any advice on how to remedy this problem.
