We will learn various manual methods to split a large PST file, and a good professional solution for risk-free use.
Let’s first discuss what are the various reasons that force users to split PST file.
Why Do You Need to Split PST File into Smaller Parts?
There are certain limitations to the maximum size of a PST file. Once the PST file approaches that limit or exceeds it, it begins to affect MS Outlook’s day-to-day functionality. The most common reasons why users need to split PST files are:
- With a large PST you can face Outlook running slow issue.
- Frequent freezing of Outlook.
- Errors during Send/Receive operations.
- A large PST file leads to corruption of the PST file.
- Data migration and Backup become challenging.
- Inconvenient to manage emails in a large PST file.
So it is recommended to split the PST file for better Outlook performance and avoid any future corruption issues.
How to Split Large PST File Manually?
There are a few methods to split a large PST file manually. We will discuss all of them in detail here:
Method 1: Use the Archive Feature to Split PST File
You can transfer older emails to a different PST file using Outlook’s built-in Archive feature.
- Switch to File > Info > Tools > Clean Up Old Items after opening Outlook.
- Select the folder or mailbox that you wish to archive.
- Decide on a range of dates. Emails sent before this date will be moved.
- Decide where to save the newly created PST file.
- Complete the PST splitting method by size or folder.
This method helps in breaking a big file, but you have limited control over the file size.
Method 2: Use Import/Export Option
Another way to split a large PST file into smaller parts is by using Outlook’s Import/Export feature.
- Once Outlook is open, select File > Open & Export > Import/Export.
- Pick Outlook Data File (.pst) under Export to a File.
- To make smaller PSTs, choose folders and apply filters.
- After you save the file, repeat the process with the other folders.
When working with a very large PST file, this method can be time-consuming, but it does work.
