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 to import the mailbox data from OST to PST file. 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.
