Split PST File – How to Deal with an Oversized PST File

Is your Outlook program taking too much time to respond? Are you unable to perform even the basic operations like opening a file, copying a folder, or downloading the embedded attachment? It seems you’re dealing with an oversized PST file that has reached or crossed the maximum size limit. The fact says that an oversized PST file is highly prone to corruption. Also, you may face some serious performance issues while using the Outlook client. In order to prevent corruption and Outlook performance issues, you need to split PST file into two or multiple parts. In this very article, I’m gonna show you how to do that.

Oversized PST File

Have you ever wondered why an oversized Outlook data file is so prone to corruption? Being an avid Outlook user, you must be familiar with the PST file size limit. The Outlook client saves the PST file in two formats: ANSI and Unicode. Microsoft Outlook 2002 and earlier versions use ANSI format that has a maximum size limit of 2 GB. On the other hand, Microsoft Outlook 2003 and later versions including the latest 2016 use Unicode format. A Unicode PST file can store the mailbox data from 20 GB to 50 GB.

Whenever a PST file reaches its maximum size limit, you’re likely to face severe performance issues like:

  • Outlook becomes unresponsive.
  • Outlook stops responding for a long time.

And the problem doesn’t end here. In fact, the situation goes from bad to worse. Because when a PST file crosses the maximum size limit, corruption is likely to happen sooner. You may lose the important emails and other mailbox data due to corruption if you don’t fix the issue in time. Learn how to repair PST file by using the Inbox Repair tool.

Outlook Error Message

Whenever any sort of problem occurs in the Outlook client, you’re likely to encounter an error message. The most common Outlook error messages are:

  • “xxxx.pst cannot be accessed – 0x80040116.” 
  • “Errors have been detected in the file xxxx.pst. Quit all mail-enabled applications, and then use the Inbox Repair Tool.” 
  • “The file xxxx.pst has reached its maximum size. To reduce the amount of data in this file, select some items that you no longer need, then permanently (shift + del) delete them.”

Sometimes it may happen that you try to add new emails or any other items to the PST file, but the PST file has already reached its maximum size limit or gone beyond it. In such a situation, the Outlook client doesn’t accept any new data. And sometimes you may receive an Outlook error message like this:

“The file could not be added to the folder. The action could not be completed.”

How to Handle an Oversized PST File?

At times it becomes a tedious task for Outlook users to handle an oversized PST file. Removing or deleting the unwanted mailbox data from the PST files one by one will definitely involve a lot of time and effort. Instead, you can split PST file into two or multiple smaller parts. You can do that in two ways:

  • Either you can import or copy the mailbox data from the main PST file into multiple new PST files.
  • Or, you can use a professional PST Splitter tool to split PST file.

First, let’s start with the DIY trick that requires no cost at all. Microsoft Outlook client contains a few built-in features which you can use here, such as ArchiveImport & Export, and Copy to Folder. If you use the Archive feature, the Outlook client will create an archive file containing the mailbox data (folder and subfolders) you’ve archived earlier. You can save this archive file at any location by any name. In the same way, you need to create multiple archive files in order to split PST file into multiple parts.

Additionally, you can use the Import & Export and Copy to Folder features to import the mailbox data. Let’s suppose that you want to split PST file into four parts. First, you need to create four new PST files. You can name them Output1.pst, Output2.pst, Output3.pst, and Output4.pst. And after that, you can import, copy, or move the mailbox data from the main PST file into the 4 new PST files one by one. Make sure you take a backup of the original PST file before you can try anything here.
