5 methods of merging PST files of Microsoft Outlook

The PST file in Microsoft Outlook contains all inbox data. If you have multiple email accounts in Microsoft Outlook, you will also have multiple PST files. In this case, it is necessary to combine all those PST files for easy management. But how to merge multiple PST files of Outlook?

Why need to combine PST files of Outlook?

There are some cases where you need to combine existing PST files into a new data file, such as:

1. Merging many old accounts
2. Combining work and social networking accounts
3. Create backups of existing accounts
4. Receive files from a group or a family member
5. Switch to another service

The above are just a few reasons why you need to merge PST files. In fact there will be many more cases.

1. Manually combine PST files in Outlook

You can combine multiple PST files (PST stands for Personal Storage Table) in Outlook. Combining PST files in Outlook is a task that can be done quickly, works with all Outlook versions from 2007 to the present. The process consists of two stages: First, create a completely new empty PST file. Then import the existing PST file.

Specific ways to do the following:

Step 1 : Select the Home tab , then select New Items> More Items> Outlook Data Files . Name the blank data file and save it.

Step 2 : Now, go to File> Open & Export> Import> Import from another program or file . On the next screen, select Outlook Data File (.pst) .

Step 3 : Browse to the PST file you want to import. You now have the option to replace duplicate files, allowing to create duplicates or refuse to import duplicate files. The choice depends on the imported PST file. This example will select Do not import duplicates . (Please remember that you need the password for each imported PST file).

Step 4 : When the import is complete, you can start the process again to import as many PST files as you want into a new PST file.

2. Merge PST Files

Merge PST Files is a free tool that you can use to merge multiple PST files at the same time. Merge PST Files is built on the manual unified PST process (as in the previous section), allowing for a comprehensive selection.

For example, Merge PST Files allows PST merge filtering by folder type, such as importing contacts or calendar folders only from different PST files.

Merge PST Files is a free tool for non-commercial use. However, it will not run in the domain environment. That's because Merge PST Files is a product developed by ReliefJet Essentials, an advanced Outlook management tool.

4. Datavare Outlook PST Merge

Datavare is a unified PST file tool in Outlook for free. This free version comes with a huge limitation. You can only merge two PST files at a time. Using the free version is similar to merging PST manually or using the free Merge PST Files tool above.

5. Stellar Merge Mailbox for Outlook

Stellar Merge Mailbox for Outlook is another free tool. Once again, the free version of Stellar Merge Mailbox only allows simultaneous merging of two PST files.

Stellar stands out among free tools for several reasons. First, the user interface is easy to use and looks more modern than some other options. Second, the premium version allows you to do more with PST files, instead of just merging them.

Instead of adding an entire PST file to a new large PST file, you can add PST as a separate directory structure. This feature will be very handy if you have detailed file structures you don't want to lose when creating a new PST.

In addition, Stellar Merge Mailbox will merge password-protected PST files without requiring that password. However, it will still need the password to access the new PST files after merging.

The above are 5 methods to combine PST files in Outlook. Manual options are very basic but useful. However, manual options will be very time consuming if there are many PST files to merge.

If there are a large number of PST files to merge, consider one of the advanced options. Stellar Merge comes with an elegant user interface and some handy settings, and ReliefJet Essentials has everything you need in a single package (though, at a slightly higher price).

Wish you find the right choice!
