How to Import OST File in Outlook 2019 Completely and Effortlessly?

OST file is a variant of PST file. Where PST stands for personal storage table, OST stands for offline storage table. It’s a kind of a cached mode allowing for offline access of your data. Anytime an IMAP email is added to Outlook 2019, it downloads the data into an OST file, which syncs with the server through internet.

But for some reason, this internal function of Outlook and the relationship between the client and the file can be broken. Often, it is caused by some corruption or damage, due to either viruses, malware, power failure, hard disk failure, etc. That can leave some data in OST file stuck, especially if there was a failure while it was trying to sync changes to the servers.

This brings to the question how to get that data from inaccessible OST file back. Or in other words, how to import OST file in Outlook 2019?

Because of the similarity between OST and PST, many users assume they can simply import it like PST. But if you go into “File” → “Import” function, you will see there’s no option for OST file import. You can only do so with PST.

The answer becomes clear then; technically OST file cannot be imported but you can convert it to PST.

It may sound simple enough at first because of the similar nature of the files, but in many ways, they are different too. It creates problems trying to convert them, especially with all the details and metadata preserved in them.
