Split PST File into smaller Parts

MS Outlook uses PST (Personal Storage Table) file format to store your mails and other mailbox items. There is a limited size of PST file and if it exceeds that size limit, then the file becomes corrupted.Microsoft outlook does not provide any facility to directly split large pst file into small pst file.  

MS Outlook uses two types of PST files, one is ANSI PST and the other is Unicode PST.

1. The ANSI PST file format has a size limit of 2 GB and was used with MS Outlook 2002 and earlier versions.

2. Unicode PST file provides up to 20 GB size limit, which is used with MS Outlook 2003 and its later versions.

Heavy and Oversized PST contributes equally in making PST management challenging. As size of PST increases more than its limitation then users have to face lots of problems.Outlook users need to manage their PST file size properly time to time. Reduction of PST files size necessary for better file management. But as you reduce PST file size, there would be possibility of data loss.

First, do try manual technique:
Just right-click any folder in one PST and then select "Move folder" to move it to another PST. If you wish to do this by date, use the unique Export feature of Outlook, and click the Filter button to select the date range. Once you have added the items to the new PST, delete them from the old PST location, because they are copied, but it still works fine.
Or else you can use the third party PST Split Software like PST Split software, Being a professional software, it provides unlimited features which not only split your large PST Files but do provide different option to split PST Files
