Thunderbird email client uses MBOX files as its default file format for storing all the data items. In the scenario of migration from Thunderbird to other email clients like MS Outlook, the data residing in the MBOX files need to be converted to a different file format. This is due to the fact that the MBOX file format is not supported by MS Outlook. Since PST is the file format that goes supported with Outlook, the Thunderbird data needs to be converted to PST file format.

There is no direct method that can convert Thunderbird data to MS Outlook. The indirect methods that can help usually turn out to be time-wasting and also do not guarantee complete conversion of data. The only way out of this is to get hold of a third-party solution that can facilitate migrating emails from Thunderbird to Outlook.

Why Users Migrate Emails from Thunderbird to Outlook?

Thunderbird users basically need to migrate their emails from Thunderbird to Outlook in case they are planning to quit Thunderbird and start working with MS Outlook. As known, Thunderbird supports MBOX file format, which goes unsupported in MS Outlook. This is due to the fact that Outlook only supports PST file format and any other file format like MBOX goes unsupported in it. Therefore, the first step towards migration to Outlook is the conversion of MBOX file to PST file format.

In order to effectively migrate emails from Thunderbird to Outlook you can deploy Thunderbird to Outlook Converter which directly converts the entire data of Thunderbird in Outlook PST format. You can follow the below-mentioned steps in order to migrate your emails from MBOX format to PST format.
