Split PST File into Multiple Parts – Try Few Easy DIY Tricks

Being an Outlook user, you must be aware of PST file size limit. The fact says that an oversized PST file can cause serious issues that include performance degradation and corruption. While opening or accessing an oversized PST file, Outlook client may start hanging or crashing frequently. And the worst consequence of having a large PST file is mailbox corruption. You may lose all the crucial email messages and other mailbox data due to corruption. In order to overcome this situation, you can split PST file into two or multiple parts.

PST File Size Limit

Microsoft Outlook stores all your email messages and other mailbox items in an Outlook data file called PST or Personal Storage Table. There are two types of PST files used by Microsoft Outlook: ANSI and Unicode. ANSI PST is used in Microsoft Outlook 2002 and earlier versions. ANSI is the default file format of these Outlook versions and has a size limit of 2 GB. As a result, it can’t store more than 2 GB of mailbox data. While Unicode PST file is used in Microsoft Outlook 2003 and later versions. It’s the default file format of these Outlook versions, and it can store up to 20 GB to 50 GB of mailbox content.

Whenever an ANSI PST file reaches its maximum size or crosses it, i.e. 2 GB, it becomes prone to corruption. Although a Unicode PST file is less likely to be corrupt, sometimes corruption can occur in these files. Corruption can cause you data loss in the Outlook data file, be it ANSI PST or Unicode PST. In such a situation, Outlook experts and professionals suggest you split PST file into two or multiple parts. How is it useful?

For example, if you have a 2 GB PST file, you can split it into four parts, 500 MB each. As a result, you’ll get four PST files which are handy in size. If PST files are handy and small in size, you’re less likely to face Outlook performance issues and corruption.
