Microsoft Outlook is an incredible tool as it allows you to keep your contacts, emails, attachments, calendar entries, tasks and so much more in one place. It does this by using two types of files – OST and PST.

Outlook uses OST file as a replica of your Exchange mailbox. It stores this file on your local system and updates it regularly to reflect the changes in your Exchange mailbox. The OST file allows you to access your mailbox when connection to Exchange Server isn’t possible or when you are offline. A PST file, on the other hand, is an Outlook file that stores your mailbox data when your Outlook is configured with POP account. The PST file is also used for creating backups of your mailbox and transferring the mailbox to different systems.  

One key difference between the two Outlook files, in terms of use, is that OST files cannot be opened directly in Outlook whereas PST files can be opened directly in Outlook. So, if you want to access an OST file, you need to convert it into PST first.

Usually, you don’t need to convert an OST file into PST as OST is simply a copy of your Exchange mailbox. However, you may face some situations when you need to convert the OST file into Outlook importable PST format. For instance, if your Exchange account is deleted, you can’t access Outlook, or if the OST file has certain “local-only” items, then you have to convert the OST file into PST to access its items.

Now that you know the scenarios in which you need to convert OST into PST, it raises the question – how do you perform the conversion? Well, the safest and easiest way to perform OST2PST conversion is by using a third-party OST2PST converter tool such as Stellar Converter for OST.
