If you want to split a large PST file into smaller parts quickly and without errors, I’d suggest trying the Split PST Tool. When my Outlook PST got too large and started to slow down my computer, I used it. Adding the PST file, choosing how you want to split it (by size, folder or year) and starting with the process are all quite simple steps. It retains all of your emails, attachments, contacts, and folder structure the same and I did not lose any data. It's a quick and easy fix, especially if you are not very tech-savvy.
