Difference Between Outlook OST and PST File: Complete Manual
Summary: In this blog, I am going to discuss information related to Outlook data files. MS Outlook generates two types of data files: the Aryson OST to PST Converter Tool. So we will gather some data related to this as well as finally jump into the main difference between Outlook OST and PST files. Microsoft Outlook is a popular client that saves email data in these two file formats: OST and PST. An OST file is created when Exchange Server synchronizes email with MS Outlook clients on the local system. Another PST file is a Personal Storage Table file, which stores all your personal emails and their attachments in your Outlook inbox.
What are OST and PST File in Outlook?
Both the OST and PST files store an exact copy of emails with attachments in the MS Outlook application. I’m talking about one of the most famous and popular email clients today, which is MS Outlook. This email management software is a powerful tool in the Microsoft Office suite. The email client comes with a regular update along with new add-on features that make the package more substantial.
In order to see the complex structure of MS Outlook, it has two files that work in the same way. Let us learn the difference between Outlook OST and PST files. But before that, Let’s know what OST and PST files are in the below context. You can also see how to Convert OST to PST Manually.
What is an OST file?
OST file is the acronym for Offline storage table, and it is located on the Exchange server; therefore, with the help of an OST file, the user can work in offline mode. When the internet connection is established again, it gets connected automatically.
The OST File is used only in the Exchange server environment, and with the help of OST files, users can even reply to the sender’s message in offline mode as well.
What is the .pst file?
PST file is the acronym for Personal Storage Table, and as the name suggests, it is located on the client’s hard disk and not on the Exchange server. Protocols like HTTP and IMAP use PST files for access. Apart from that, the PST file is stored on the server with whom the client is syncing but never on the Exchange server because a copy of the PST file is already saved there as an OST. Emails that tend to be sent and received are also stored in the PST format. Not only do PST files store calendar entries, attachments, and tasks regarding to-do lists, but contacts as well.
What is the difference between Outlook OST and PST files?
Although the MS Outlook software deals mainly with the management of emails, But apart from that, it has embedded features that work amazingly well with the management of calendar tasks, to-do lists, contacts, and many others.
Rather than exaggerating the topic, I will dive right to the moot point, which expresses the difference between Outlook OST and PST as follows:
- OST is an Offline storage folder that helps the user work even in offline mode. On the other hand, PST is the folder, which is a personal storage table that works online.
- OST files are bound to the Exchange server only. But PST files can or cannot be used with the Exchange server. With this feature of PST, it can be used or synced with other mail servers as well.
- OST folder can also be used when the user is online, irrespective of the mode in which OST works efficiently. PST, on the other hand, saves local data.
- With their high efficiency, OST files provide the ability to work online, like composing, sending, and receiving mail, in offline mode. Otherwise, PST doesn’t work this way.
Conclusion
As we discussed above, Both the OST and PST files store an exact copy of emails with attachments in the MS Outlook application. We also described other things about an OST or PST file.
