What are the Differences Between OST and PST Files?

Difference Between OST and PST

If you are Microsoft Outlook user, then it is important for you to know that all emails, calendar, contacts, tasks, and other data items are saved on a local system, on a mail server, or both. Moreover, MS Outlook data items that are stored on the system are named as Outlook Data File with both .pst and .ost file format. Now, why there are two file formats to save data? What exactly the difference between PST and OST files used in Outlook? To resolve all such queries, a deep comparison of OST vs PST is done here.

In MS Office Suite, Microsoft Outlook is the widely used application among the business users. It is an email client that allows users to exchange information in an organization using its mailing service. Apart from this, other available services are contacts, calendars, tasks, notes etc. Now, to store all data items there is two type of file format supported by Outlook i.e. PST and OST file format. PST file format is created for each user account configured in Outlook to maintain copies of emails, contacts, calendars, tasks, notes etc. If Outlook is connected with Exchange Server, then all items are delivered to and saved on the server. However, if a user wants to have access to data when not connected server, then OST file or Offline Storage Table is stored on the system.

Both OST and PST files are data files of Outlook but they are completely different from each other in many ways. Thus, to understand both in a better way, the difference between OST and PST is done in the following section of the blog.

OST File PST File
Offline Storage Table is commonly known as OST file of MS Outlook. It is created by Microsoft Exchange that holds all offline copies of each data items in MS Outlook such as emails, entries in calendar entries, notes, tasks, contacts and much more PST basically stands for Personal Storage Table. Microsoft Outlook store all data items i.e. emails, contacts, calendars, tasks, etc., of the mailbox in PST file format.
It is generally a replica of Server folder which can also be called as slave replica of Exchange Server. It is standalone and self-contained file format, which represent how messages are stored in MS Outlook displaying an arbitrary hierarchy of all folders.
OST files can only be accessed through the MAPI profile that created it originally. Whenever it is created with the POP3 account, OST file is created. Moreover, can access in any other Outlook profile also very easily.
One can easily access OST file when Outlook is connected to Exchange Server. Using this, one can easily edit, compose or delete email messages in offline mode. It gets synchronized automatically whenever a connection is established again. One can store PST file of Outlook anywhere on the system that can easily used as a backup and move to another system if a user wants.
One can easily use OST file folder when there is no internet connection. PST file folder cannot be used in limited or unreliable connection area.
OST file default location:
  • Windows 7 & Windows Vista:drive:\Users\user\AppData\Local\Microsoft\Outlook
  • Windows XP: drive:\Documents and Settings\user\Local Setting\Application Data\Microsoft\Outlook
PST file default location:
  • Windows 7 & Windows Vista:drive:\Users\user\AppData\Local\Microsoft\Outlook
  • Windows XP: drive:\Documents and Settings\user\Local Settings\Application Data\Microsoft\Outlook

The main purpose of OST file is to allow users to work in an offline mode. It is mainly used by the users who want to keep their data safe and secure. If one is not connected with the Exchange Server, then also with the help of OST file one can work offline and work gets synchronized automatically when the connection is reestablished. Moreover, in the case of corruption in Exchange Database, a user can recover data from OST file saved on the drive. On the other hand, Personal Storage Table and PST file allow users in increasing the storage. It is the file that can easily be backed and can be accessed on any other computer also. In the case of large size PST file, one can easily split the PST file by date, year, size and much more. It helps users in managing their Outlook mailbox in the more synchronized way and prevent corruption.
