Import OST to Thunderbird – An Ideal App Built for Everyone!

Import OST to Thunderbird. The Outlook file that doesn't even open in Outlook manually, how to import it in Thunderbird? Find the best solution here.

Import OST to Thunderbird – Directly It is not possible to import. But you can convert the OST file to Thunderbird supported file format. Here is the details topic on OST/PST and Mozilla Thunderbird.

The OST & PST files

OST and PST are two variants of the Windows Outlook file. OST is for offline storage and PST is for personal storage. You can choose in Outlook settings what file you want to use for downloading and storing the emails at. But by default, anytime you add an IMAP or Exchange account to Outlook, all the emails while syncing from the mail servers are downloaded to OST file.

This lets you access data even offline. You can also make changes in an offline mode and even send an email (which will be kept in Outbox folder). When the connection to internet is back, Outlook automatically synchronize the changes with the mail servers. This keeps your database same everywhere.

PST is used when you add a POP account, which is relatively an older protocol for accessing and downloading mails from the servers. With a POP enabled email account and PST file, the emails are simply downloaded to your local machine for you to read them. But it doesn’t change anything on the servers. If you delete an email, it will remain on the servers because there are no active synchronization in place. (though, many email services allow deleting the email once the client like Outlook has requested for downloading an email).

Many do not know about this mechanism and they often don’t need to.

However, the trouble starts brewing when there is OST file and nothing else. Because that is impossible to import OST to Outlook or open with Outlook (or any other client) without the original email account it was associated with.

That is just the nature of OST file. It is not meant to be used manually for tasks like importing/exporting, archiving, migrating, or doing anything with the data. The file format works internally and automatically with Outlook for the seamless functioning with the client and the servers.

But any how you have the OST files you with and you want to import or migrate it to Thunderbird. Such projects of import OST to Thunderbird can be frustrating, considering the file is not even import-able with the Outlook.

But, here is what you need to hear:

It is possible to import OST to Thunderbird, though, not directly. By converting it to the format that Thunderbird can detect and import, you can move the data in OST to the client.

You can also use OST with Outlook (both Windows and Mac) if you convert it to PST.
