You can delete duplicate PST files because it many numbers of repeated PST emails. I can suggest one software becouse I'm aslo using this tool, so I prefer a good method to delete PST duplicate files with "SameTools Remove Outlook PST Duplicate". This tool can handle a large number of duplicate PST files, like emails, contacts, etc, without any glitches. The software supports all Windows OS versions like 11, 10, 8.1, 8, 7, and aslo supports ANSI and UNICODE. You don't need to use MS Outlook, and this software doesn't affect your important data. Try the free demo before buying this tool.
