Personal Storage Table (PST) is the format of a data file that MS Outlook creates locally on your computer to save emails, contacts, drafts, notes, journals, calendar items and inbox information. These files can be used for the purpose of archiving emails and storing them on local computer. Personal storage files are very important, because if these gets corrupt, the user cannot access his mailbox.
This file extension created by earlier versions of MS office, had a size limit associated with them that means, the size of these files could not exceed the limit of 2GB. On crossing this limit, either the Server may crash or the mailbox tables of Outlook may get corrupt and unreadable. Microsoft Outlook has an inbuilt tool, ‘scanpst.exe’ that can be used to recover such corrupt mail files. However, this tool often did not work if the amount of damage in personal mail tables was major.
In order to reduce the damage in personal storage folders due to size limitation, changes in the character format have been made in new Outlook versions, which support both UNICODE and ANSI character formats. Therefore on these latest mail versions, size of PST can be up to 20 GB. The latest version of MS Outlook i.e. 2013 and 2016 supports UNICODE character format and the file sizes created using this has the default size limit of 50 GB, which can be modified by making some changes in the Registry entries.
