PST Recovery – Perform Your File Recovery Effectively

What is a PST file ?

PST stands for personal storage table. It is a file format for the data files which Outlook uses in order to store all the Outlook data which includes data like emails, contacts, calendar etc. These data may or may not be compressed or encrypted depending on the settings of your Outlook. When more data is stored in your PST file then it is noticed that the Outlook performance becomes slow. For this the Outlook offers to archive the old emails in order to help remove this problem.

Outlook data files are of two types. These are Outlook Data File .pst and Outlook Data File .ost.

  1. Outlook Data File (.pst): An Outlook Data File .pst is used for POP3 and IMAP email accounts. Whenever you want to create an archives or backup files of the Outlook folders and items on your system for example Exchange accounts then you should create and use an additional Outlook Data File (.pst)
  2. Outlook Data File (.ost): Outlook Data File .ost is used when you have an Exchange account and chose to work offline or you use Cached Exchange Mode. It’s not necessary to keep backup of an offline Outlook Data File (.ost). A new Outlook data file .ost is created from the saved data on your system.

OST file are same format as PST but is used as an offline storage. PST file are used for the email archival. POP3 and IMAP accounts email may be stored in a PST file whereas email synced from Hotmail account with Hotmail Connector is stored in an OST file. Exchange accounts can use both an OST file for offline access and a PST file for data backup.
