To merge PST files, follow these technical steps. First, open Microsoft Outlook and create a new PST file. Next, import the PST files you want to merge into the new file. Ensure that you have a backup of the original PST files before proceeding. Use the "Import and Export" wizard in Outlook to import the data. Once imported, organize the data within the new PST file as needed. Finally, compact the PST file to optimize storage.
