Best Method to Merge PST Files without Duplicates

Summary: Managing PST files for multiple Outlook accounts isn’t just a mess, but a disaster. From missing attachments to duplicates and cluttered mailboxes, the result can often be frustrating. But what if there were a way to merge PST files cleanly, efficiently, and without duplicates? This guide provides the most effective methods and introduces a specialized PST Merge Tool, enabling you to easily organize your mailboxes and combine Outlook PST files.

Merge Multiple Outlook PST Files: Know Why?

There are some substantial reasons that a need to combine multiple PST files into one file arises. These are:

• Outlook struggles with scattered PSTs in the mailbox, which generally slows performance.
• To reduce the fragmentation and consolidate PST archives all in one place.
• It is quite easy to maintain, access, share, and backup a single PST file.
• Merging PSTs helps simplify the search and conduct eDiscovery for specific items quickly.
• Suitable to avoid redundancy and opening the same PSTs again and again when in a hassle.
• Avoids the situations of data loss, corruption, or misplacement, especially for crucial ones.

How Do I Merge PST Files Effectively?

While searching for an appropriate solution to combine several PSTs into one, I found this easy and simple manual method. But what made my task much quicker without so much effort was the professional tool discussed at the end. You can get to know all about them here.

Note: Before you proceed to merge duplicate contacts in Outlook or even any other data, it is essential to take a backup of the same. A backup ensures that you will still have your crucial data at the end, if something goes the other way.

Manually Combine PST Files into One

This is the only free solution available to merge PSTs naturally. It involves the use of the MS Outlook application and its well-known Import/Export feature. Moving on, we have provided this method in two parts for a swift understanding:

1) Creating a New PST File (Blank)

1. Launch Outlook, click on File, and then access the Settings section.
2. Now, go to the Data Files tab and click Add.
3. A dialog appears with format automatically set to Outlook Data File (.pst).
4. To create a blank PST, simply give it a name and a location, then click OK.

2) Merge PST Files by Import

1. Further, acquire and open the Import/Export wizard. (In, File → Open & Export.)
2. Here, click “Import from another program/file” and Next.
3. Next, select “PST” and then tap Next to continue.
4. Tap the Browse button and select your .pst file to merge with Open.
5. After that, from options in the same pane, choose Do not import duplicates.
6. Click Next and pick the specific folders to import data from in the new PST.
7. Next, under “Import items into the same folder in,” choose the blank PST you just created.
8. Finally, click the Finish button to merge Outlook PST files into one.

Drawbacks of This Method:

• You’ll need to repeat this process for each PST file you want to merge.
• The duplicate deletion is limited only to the subject and timestamp, and not to other advanced features.
• It requires a lot of effort and time to merge many Outlook PST files into one single PST.
• There is a high risk of nested folders and inconsistencies in the data present within the PST file.
