Managing multiple PST files in Microsoft Outlook can be tricky. If you use Outlook for work, personal, or archived emails, having several PST files can make it hard to find and organize data. The best way to simplify this is by merging PST files into one.
In this blog, we’ll show you two easy ways to merge PST files in Outlook 2021, 2019, and 2016 — manually and automatically using the Advik PST Merge Tool.
What Is a PST File?
A PST (Personal Storage Table) file is an Outlook data file that stores your emails, contacts, calendar events, notes, and tasks. Every time you create a new Outlook profile or backup, a new PST file is created. Over time, these files can multiply and become difficult to manage.
Why Should You Merge PST Files?
Merging PST files has several advantages, such as:
Keeps all your emails and contacts in one place.
Prevents data duplication.
Makes Outlook run faster and more efficiently.
Simplifies data backup and management.
Helps in transferring Outlook data to another computer.
Method 1: Merge PST Files Manually in Outlook
You can merge PST files manually, but it takes a few steps. Here’s how to do it:
Step 1: Create a New Blank PST File
Open Outlook 2021/2019/2016.
Click on File → Info → Account Settings → Account Settings.
Go to the Data Files tab.
Click Add, choose a location, and give your new PST file a name.
Step 2: Import Data from Existing PST Files
Go to File → Open & Export → Import/Export.
Choose Import from another program or file → Click Next.
Select Outlook Data File (.pst) → Click Next.
Browse and select the PST file you want to import.
Choose the folder (Inbox, Contacts, etc.) where you want to import data.
Repeat this process for every PST file you want to merge.
Note: This process can be time-consuming and requires manual effort, especially if you have multiple large PST files.
