How can I remove duplicate emails, contacts, and calendars from PST without Outlook?

I have a large PST file that contains many duplicate emails, contacts, and calendar entries. The problem is that I cannot use Microsoft Outlook on my system right now (Outlook is not installed / not working properly), but I still need to clean this PST file. I am looking for a reliable and safe way to remove duplicate emails, contacts, and calendar items directly from the PST file without opening it in Outlook. I also want to make sure that the original folder structure and data are not damaged during the process. Has anyone faced a similar situation? Please suggest a trustworthy solution to remove PST duplicates without Outlook.

If you have many duplicate emails, contacts, and calendars from PST files without Outlook. I'm also facing the same problems so I can suggest a perfect tool for it. You can try the GainTools Outlook Duplicate Remover tool, which can quickly identify duplicate items in the PST files like emails, contacts, calendars, notes, etc, and remove them within a few clicks. The software handles a large number of duplicate files from PST without losing original data. There is no need to download MS Outlook on the PC. The tool saves your time efforts and improves performance. The software works with all versions of Windows OS, like 11, 10, 8.1, 8, and 7. Non-technical users can also use it without technical skills becouse it has a user-friendly interface. You can use the free demo versions before buying this tool.
