How to Merge Multiple PST Files into One?

Hello, you can easily merge your multiple PST files into a single file using manual techniques. This process has two steps, first, you have to create a new PST file and second import old PST files into the new one.

Here I am going to tell the complete steps of merging multiple Outlook PST files.

Step 1: Create a new PST file

• Run Outlook application and click on Home tab
• Click New Items >> More Items then click Outlook data file.
• Now, choose a location to save a new PST and provide a name for it.
• Click OK. Your new PST file is successfully created

Step 2: Import Old PST Files to a New PST

• Click on File tab >> Open & Export >> Import/Export
• Select Import from another prgram or file option and click Next
• Select Outlook Data file (.pst) and again press Next
• Browse the PST file to import and click Next
• Select the folder you want to import
• Finally, click the Finish button

Hi David, If you’re looking for a manual fix, this is the only process where multiple Outlook PST files are merged. If you’re looking for an alternative solution, you’ll need to use third-party tools that are also helpful in merging .pst files.

You can try SysTools PST Merge Tool, which lets you merge multiple .pst files into a single file. This software is useful for all types of users, including professional and non-professional users, because it has a simple user interface.
