How to Change PST File Size Limit in Outlook 2013

Microsoft Outlook is one of the most preferred email client used for email communication. It stores user emails and other information in PST file. There are certain size limits to the pst file beyond which the information can’t be stored. Once the file reaches that limit Outlook doesn’t behave normally and sometimes results in corruption of PST file thus making emails and other information inaccessible.  The latest version of MS Outlook i.e Outlook 2013 has pst file size limit of 50 GB which is enough for some users but if you use Outlook extensively you can set the size of pst file to a higher number. In the article I will guide you on how to change pst file size limit in Outlook 2013 by editing registry entries.

The four registry entries which are determined to limit the size of PST file are:

  • MaxFileSize
  • WarnFileSize
  • MaxLargeFileSize
  • WarnLargeFileSize

While  MaxFileSize and WarnFileSize registry entries are used with UNICODE pst file MaxLargeFileSize  and WarnLargeFileSize registry entries are used for ANSI pst files.

MaxLargeFileSize – The value in this registry entry sets the maximum size of Unicode pst.

WarnLargeFileSize – The value in this registry entry sets warning level used with Unicode pst files.
