If You Are Trying to Open OST in Outlook, Don’t Bother! Here’s What Works Instead!

Open OST in Outlook – Why & How

Looking to open OST file in Outlook? There are two things you want to know, one of which isn’t good news but the other one is. First: OST cannot be simply opened in Outlook. Second: there is a solution to get the data in OST into Outlook.

What is OST and PST file?

OST is a file that Windows Outlook uses to store data. It is in many ways an internal and functional file for Outlook, not intended for many manual tasks. You cannot manually export data to an OST file and later import or restore it back. OST main function was to let users work with emails even offline and the changes made while offline are synced to the servers once the internet is back up.

There are some misunderstandings that evolve from mixing up OST and PST. PST was the first native file for Windows Outlook. It was an acronym for ‘Personal Storage Table.’ OST on the other hand stands for Offline Storage Table. So, the primary difference being that OST is not a personal data file and has no use outside of Outlook itself. It cannot be used to migrate, backup, or restore data.

However, the misunderstanding of OST file leads to problems like keeping OST file as a backup. Under the false hope of restoring it when needed later in future.

Another frequent cause of why users are often stuck with OST file is that they delete their original email account while the data was still in OST files. If the changes you made or the data in OST was not synced to the servers, you are stuck with it. If you delete the OST file manually by going into the profile folder, Outlook will automatically create another one when you launch Outlook the next time. But to delete the email account in the first place will render the OST file associated with the account useless.

So, if you want to open OST in Outlook or want to import OST files in Outlook, don’t bother. It is simply not possible.

However, the good news is that you don’t have to simply forget the data you have in OST file with bitter heart. There’s a way to get the data restored from OST files to Outlook, and even Mac Outlook for that matter. The way to go about that is by using a third-party tool that can convert the data from OST into PST. And then PST can be imported to Outlook. By just adding one simple step – file conversion – you can get the same output of importing data that would otherwise be stuck in inaccessible OST files.
