The software converts OST to PST and can convert multiple OST files into PST format.

In short

 OST and PST files are both data files for MS Outlook. They hold all the mailbox folders, such as email messages, contacts, calendars, journals, notes, tasks, and more. When the server crashes for no apparent reason, such as due to malware, spam emails, virus attacks, or power outages, it is necessary to convert OST data to PST format. In this article, we'll discuss how to convert OST files to PST files. You may use the Import/Export Feature, Auto Archive Settings, or other tools to convert an OST file to a PST file format. You can convert OST files to PST format by hand, or use the OST to PST Converter Tool, which lets you convert many OST files to PST format at once.

Getting Started with OST and PST Files

Offline Storage Table and Offline Outlook Data File (OST) files save a copy of the mailbox data on the server. It lets people work even when they can't connect to the server. As a user, you may simply modify, write, add attachments, save emails, and delete email messages and other mailbox objects. When you connect to the Exchange Server again, these modifications will be up-to-date.

PST, on the other hand, stands for Personal Storage Table. It is the most common Outlook data file type and works with or is produced by MS Outlook, such as EML, MSG, and OST. It saves copies of all the things in the mailbox, such as email messages, contacts, calendars, tasks, and journals, to the user's local disk from the account set up in Outlook using POP. Using the Import/Export Feature's Export to File option, you may quickly make the PST file. You may also password-protect your PST file, which means you have to input the password every time you access it.

How OST and PST Files Differ?

If you want to know why it's crucial to convert OST to PST, here's a comparison of the two formats side by side.

  • If you have an online connection, OST files will automatically sync changes with the email server. PST files, on the other hand, only let you handle them in MS Outlook if you have an internet connection.
  • OST files can only be used with Microsoft Exchange Server, and PST files can also be used with other services like Microsoft Exchange Client and Microsoft Outlook.
  • The client saves all emails and appointments from IMAP and MAPI accounts in an offline storage table (.ost) file from Microsoft Outlook 2016. Before that, it utilized the PST file for IMAP or MAPI accounts from Outlook 2013.
  • You may use the ScanOST.exe utility if there are any little problems with corruption or access in the OST. Microsoft Outlook does provide a ScanPST.exe utility to assist users in curing any Outlook PST file problems in case the PST file becomes corrupted or damaged.

What are the Benefits of Converting OST to PST?

The need to change from OST to PST format arises for a variety of reasons. Here are a few of the most typical explanations:

* Importing OST Data: Users sometimes wish to move mailbox data from one system to another, but it might be hard with an OST file.
* Avoid the Risks of Losing Data: Your Exchange OST file may have been too big, broken, or corrupted. So, you may change OST to PST to get around the mailbox size limit.
* Accidental Deletion of Exchange: Let's say your Exchange Server isn't running or the Exchange data is erased for some reason. In such a situation, it would be advisable for you to convert OST files to PST files first.
* Access the Data in Online Mode: If you want to open or change your OST file that is stored offline in Outlook PST format.
* Changing Email Clients: The OST file doesn't work with any other email clients than Exchange and Outlook. So, to move old mailbox contents to other email clients, you need to change the OST file to a PST file.
