Multiple Ways to Split Large PST file in Microsoft Outlook

Outlook by default stores all its mailbox data into a single file that is “PST” file. It stands for Personal Storage Table. It is obvious that when the Outlook stores data in PST file the size of the PST will get bigger. User finds it difficult to deal with bigger PST File.

Outlook has set particular size of PST for different version, From Outlook 98 to 2002 the size limitation is 2 GB and from 2003 to 2016 it’s 20GB. Once you reach the PST file size limit, the performance of the Outlook slows down as a result Outlook hangs or freezes during launching. Or sometimes it gets corrupted. Below are some issues that found due to increased size of PST:

  •       Outlook PST file prone to corruption
  •     Slow Performance of MS Outlook 
  •      Outlook hangs during launch or closing
  •        Fails to send or receive emails

The above issues are the most common problems confronted by the Outlook users. However, To avoid this type of error it is advised to manage the size of the PST file by splitting it into multiple smaller PST.  Splitting the PST file into small PST creates multiple PSTs files which are easy to read, searched and along with this there is no risk of corruption. PST file corruption is undoubtedly a matter of deep concerns for Outlook users.

There are various methods available by which you can split the size of your PST file.


MS Outlook offers built-in features which can be used for making the PST file small. There are three such features available with all Outlook version.
