Convert OST files to MBOX files, Here is an excellent software to convert each and every data from OST files into required file format (*.mbox, *.ics & *.vcf).
Converting OST files
OST file converters are often not efficient enough to be practical. One of the reasons is the complexity of OST file. It varies greatly from other data files in email clients. And, it is not even possible to import it in Outlook, the client for which it is the native file. It is, then, very tricky to convert the data inside it for other email clients, such as Thunderbird or Apple Mail.
This post deals with converting OST files to MBOX files. The reason many people want to convert data to MBOX because MBOX is compatible with many popular software and is a standard format that can also be used as a backup.
So, back to the question – how do you convert OST files to MBOX files in a way that does not mess up your productivity or the integrity of your data.

Email databases, such as stored in OST files, extend way beyond mere emails containing text. If you take a look at your mailbox folders in Outlook, you will find many different types of content. To migrate all of this without exception requires a steady and precise application that does not gloss over any information. If the output MBOX contains any erorrs, missing components, or even undesired changes, then that is called data integrity compromise, and is a big concern for any user wanting to migrate emails.
