Written by Rohit Singh

Do you want to find the finest PST merging tool? If you answered yes, you’ve come to the correct spot. Today I’ll go through the simplest approach to merge multiple PST files into one. Unfortunately, several customers are having difficulties managing numerous Outlook archives. As a result, only a few professional solutions are available to merge PST files into one PST.

I picked the top 10 best PST Merge Software of 2021 after evaluating more than 20+ options. The following rating is based on speed, performance, accuracy, dependability, functionality, and user-friendliness.

What is PST Merge Software?

PST Merge Software allows you to combine or merge several PST files into a single file. This tool may be used to combine PST files in Outlook 2019, 2016, 2013, and 2010 without causing size, data loss, or security concerns.

Why does PST Merge Software need to Merge PST Files?

Outlook users may require the merging of PST files for a variety of reasons. Some of the most prevalent explanations are:

Merging Numerous Outlook Accounts: If you use separate email accounts for personal, work, and social media correspondence, you may have multiple PST files. Just merge the PST files and import the resulting PST into a new account to unify these accounts.

Upgrading to a Newer Outlook Version: The largest supported PST file size in earlier Outlook versions, for example, Outlook 2007, is 20 GB. As a result, users of this Outlook version had to create several PST files to hold all of their emails. The maximum in recent Outlook versions (2010 and higher) is 50 GB. So, if you’re updating to a newer version of Outlook, you can combine existing PST files into a single PST.

Switching to a Different Email Client: You may merge all of your PST files into a single PST file if you move from Microsoft Outlook to another email client. When all of your data is in a single file, you can quickly move your emails and other mailbox items to the new platform.
