The quickest way to combine multiple PST files into a single file in Outlook 2025 is to use a professional solution such as the Softaken Merge PST tool. Manual merging in Outlook is time consuming and risky because you have to import/export each file individually, with the possibility of data loss. This software allows you to quickly merge multiple Outlook PST files (emails, contacts, calendars, tasks, journals and attachments) into a single, unified PST without losing data. It also allows merging without size restrictions and keeps the folder structure and information intact throughout the process. The tool has a basic interface, so even if you are not a technical expert & you can operate it without difficulty. After merging, just import the newly generated PST into Outlook 2025 for easy access. This makes handling several PSTs much more convenient and efficient.
