MBOX files, also known as Mailbox files are supported by an extensive range of email clients as their default database. A MBOX file stores all the emails of an email client in a single concatenated structure. The emails are separated from each other with the header information of the subsequent email. The email clients, which support MBOX file, are Thunderbird, Sea Monkey, Pocomail, etc.
On the other hand, PST files are the default database format for storing Outlook database. Unlike MBOX file, PST file is only supported in Outlook.
Reason behind MBOX to Outlook PST Conversion
There are times when a user working with MBOX supporting client, say Thunderbird may need to migrate to Outlook. This migration can be a way to seek more efficiency and advance emailing features, which Outlook offers. Since Outlook only supports PST file, accessing MBOX file in Outlook is not possible. Therefore, in order to migrate to Outlook, the user needs to convert the MBOX file data to PST format.
Manual Conversion of MBOX to PST
In case the user is working with Thunderbird email client, the MBOX data can be accessed in Outlook via a manual process. In this process, the Thunderbird emails can be exported via EML files. These EML files can later on be imported in MS Outlook.
Limitation: this method is only applicable for Thunderbird email client. Therefore, the other email clients, which support MBOX, will not support this manual procedure.
MBOX to PST Conversion
Thus, it is evident from the above section that is manual method with the help of which the MBOX file can be converted to PST format. Therefore, the only way to convert MBOX file to Outlook PST format is by deploying third party tools like MBOX to Outlook Converter. The software supports the conversion of MBOX files belonging to any of the email clients to Outlook PST format. A complete preview of the MBOX file is generated by the software and the user can easily convert a selective amount of data from MBOX files. The software offers split PST option, which enables the user to split the resultant PST file into smaller PST files.
