OST and PST are two Outlook data file types. OST is an offline storage table whereas PST is a personal storage table. Both these Outlook data files store exactly the same type of mailbox data. However, OST and PST files are different from each other. Sometimes it may happen that a user needs OST to PST conversion. There might be any reason for that, and we’re going to discuss them in this article.
Difference between OST and PST
Microsoft Outlook offers a wide range of features to fulfill the messaging needs of businesses and organizations. In offices, the Outlook client is used for both internal and external communication. Apart from being an email client, it works as a personal information manager. It creates an Outlook data file to store email messages, contacts, calendars, tasks, notes, journals, as well as attachments. There are two types of Outlook data file: OST and PST.
If you’re using the Outlook client as a stand-alone application, it creates a PST file to store the mailbox data. Generally, a PST file is used for POP3, IMAP, and web-based mail accounts. On the other hand, the OST file is created when the Outlook profile is connected to the Exchange Server and the Cache Exchange Mode is enabled. It stores all the mailbox data in an offline mode on the local computer system. It works as a mirror image of the Outlook mailbox data on the Exchange server. You can work with an OST file even if there’s no network connectivity. And when you log in to your Exchange account when the network connection is re-established, all the changes will be synchronized into the Exchange folder.
OST to PST Conversion but Why?
These days “OST to PST conversion” has become a hot topic on the Internet. Do you know why and when it’s required to convert OST file to PST format? Well, there are many reasons for that. Below are the top 6 scenarios when it becomes extremely necessary to import the mailbox data from OST to PST file:
Exchange Server Crashes Down
Almost every computer application is prone to crash. There are many reasons due to which an Exchange Server may crash down. Some of the main reasons include internal bugs, abrupt power failure, virus infection, software malfunction, etc. Whenever an Exchange Server crashes down, the connection becomes unavailable. In such a situation, you can’t connect to the
Exchange Server until you repair it. It may take some time to repair the Exchange Server. Although you have an OST file, you can’t use it online. In order to use the mailbox data of the OST file in online mode, you can convert the OST file to PST format.
Exchange Server Goes for Maintenance
Microsoft Exchange Server needs proper maintenance in a regular manner. And you can’t access the mailbox data if it has gone for maintenance. But sometimes it may become extremely necessary to access the mailbox data. Although the OST file contains the mailbox data, it only works with synchronization with Exchange Server. If you urgently need to access the mailbox data online, you can convert OST to PST file format.
Your Outlook profile was connected to the Exchange Server in the organization you were previously working. Now you’ve switched to a new organization. Although you have the OST file, you can’t use it online. There’s a limitation in the OST file. It can only be opened on the system where it was originally created. In order to use the OST file data online, you must convert it into PST file format.
OST to PST conversion may become an essential task if you’re migrating the data from one place to another. Especially when your organization is shifting, you need to move all your important data to a different system. Although an OST file can only be opened in the system that originally created it, you can overcome this limitation by converting it into PST file format.
Recovering Data from OST File
If you delete some of the mailbox data from an OST file accidentally, you can simply download the new OST file from the Exchange Server. In this way, you’ll restore the data which you’ve deleted earlier. But how would you recover the data if it has been already deleted from the Exchange Server? By converting OST to PST file format via a professional OST to PST Converter tool, you can recover the deleted items as well.
No computer file is immune to corruption. An OST file is likely to be corrupted due to various reasons, such as virus infection, software malfunction, abrupt system shutdown, hard disk failure, lack of storage space, server crash, etc. Though Microsoft provides the Integrity Check tool (scan ost utility), it may not work if corruption is severe. In such a situation, you can convert OST file to PST format by using a professional OST to PST Converter tool.
