This post is about how to convert .OST to .PST file in the best way possible. You can get the free download of ‘OST Extractor Pro’ that features the advanced algorithms to convert data accurately. But before we talk about the tool and how it works, first let’s get the basic background information about the conversion task out of the way.

.OST and .PST Files – And What Are They?
Windows Outlook automatically creates an OST file when you add an IMAP or Exchange based email account. All the data is downloaded into an OST file. OST file serves as an exchanged copy of your mail data that you can access even offline. The changes made in an offline mode will get synced to the servers once the connection is back up. It only stores emails.
On the other hand, PST file is usually a backup copy of your data. You can manually archive everything including emails, contacts, and calendar entries into a PST file. And its capacity for storing large data makes it a useful file format. It is also used with POP3 email account. And you can manually change the settings of your Outlook to store data into PST for an IMAP or Exchange account, but it is not recommended for several reasons. One of them is that any changes you will make to the PST file will not be synced to the servers, and will remain only locally on your computer.
Where does .OST to .PST conversion come from?
So, why does one need to convert .OST to .PST?
There could be few cases where converting .OST to .PST is required. Since you are on this page, it may be possible that you have one of those requirements:
OST file is not used for importing, backing up, or migrating data. The file is only associated with the email account that created it in the first place.
If you delete the file, Outlook will create another whenever you open it the next time. But if you delete the email account itself from Outlook, the OST file downloaded will be useless. Now, if you have synced all the changes you made to the file offline on to the servers, you will be fine. But if not, all your changes will be stuck in an inaccessible file. Most users try to import the OST file into Outlook, which doesn’t work. Outlook doesn’t support that feature because the OST format isn’t developed for that purpose.
Without deleting the email account, you can still face the problems where Outlook would be having trouble connecting with the OST file and syncing the data correctly. This can be due to many factors, like viruses, network errors, hard drive failures, power failures, unexpected shutdown of computer, and so on. All these factors can damage the connection between OST and Outlook, or the OST file itself.
But, largely, they do not damage the data itself within the OST file. If they do, you will need a recovery tool. But largely, they do not, and that leaves you with one option to get your data from inaccessible OST files into Outlook – by converting .OST to .PST.
How to Convert .OST to .PST?
At last, we are back to our main topic for the post. How to convert .OST to .PST files?
Sadly, there is no inbuilt feature inside Outlook that can help you with that. ScanOST.exe is a program from Microsoft that can help you recover the damaged OST files. But as said above, if it’s not the damage to the file itself, the program won’t help you much. You need a third-party file converter to convert the format itself to PST.
Why to PST? Because PST is a typical data file that is used for importing, exporting, migrating, backup, etc. So, you can convert OST to PST files, and then simply import PST into Outlook and you will get all your data back.
Other unfortunate fact remains that most of the third-party converters are very limited and inefficient with their features and algorithms for data conversion. It should be noted that the extraction and conversion of files is rather complicated and cannot be pulled off by simple and poorly developed algorithms.
And that’s when “OST Extractor Pro” comes into play.
