Here we will take a look at how exporting Outlook OST to Thunderbird is nothing like what ordinary tools have made you believe.
Before we proceed further, let us take a quick primer of the task and everything involved.
Outlook OST:
Outlook is a client for Windows platform, and OST is the native file Outlook uses to store content. There is also a PST file but here we are only concerned with the OST.
Thunderbird:
It is a cross platform email client used in Windows, Mac, and even Linux. One of the best free and open-source software for emails that is widely used and appreciated by many.
Outlook OST to Thunderbird Email migration:
If you are switching to Thunderbird from Outlook, you need to export all your data as well. If all emails are on the servers, you can simply let the data sync from the server to Thunderbird after adding your original email account. But the local data in Outlook (not on servers) cannot be simply moved to Thunderbird by moving the files.
This is because no file in Outlook supports Thunderbird environment, neither OST nor PST. OST is not even usable in Outlook client itself.
Therefore, what you are left with is the data conversion of the files. You need to convert OST to Thunderbird using non-official converters.
If you have ever performed this task, you know how complicated it can get. Most of the times, users end up with incomplete data, full of missing component and metadata errors. Sometimes, the structure of fodders is all messed up, making it harder for you to arrange and find emails.
But if you think this is normal and expected and no way to avoid it, you are in for a surprise.
There is a company that has been reconstructing and shifting the paradigms of many email migration projects since years. This time they are back with the Outlook OST to Thunderbird task with OST Extractor Pro.
