OST to MBOX Converter

OST files are a proprietary file format belonging to Microsoft Office Outlook 2013 and onwards.They were meant as a change from the traditional idea of hosting every conversation, address book and contact on the email provider's server.  Instead, these files are saved on your hard disk and can be accessed even when the Internet connections are down. Unfortunately, OST isn't a format that can be accessed by many applications, and require conversion into other more accessible formats. That is where OST to MBOX Converter comes into the picture, as it allows you to convert OST files into MBOX format fast and easily.

As the name of the program says, the conversion process goes fast and easy thanks to the ridiculously simple UI. All you have to do is browse for the location of your account's OST file, select whether you want your messages to be separated or displayed in a single text file, and then choose a destination path. Depending on how many messages there are to process, the conversion can last anywhere between a few seconds to a couple of minutes.

The app separates the content by type (contacts in one folder, Inbox in another) so you don't have to worry about going through a long text file when looking for something. One drawback compared to other OST converters is that the app doesn't let you preview and select certain sub-files from your OST file since it converts everything instead. Depending on the overall size of the OST file, this could lead to long waiting times.

The app is easy to use, so it is a must-have for those who don't want to go through the hassle of managing parameters and settings when converting a file.  Unfortunately, the fact that it doesn't allow you to select precisely what parts of the OST file to convert makes OST to MBOX Converter only good for either beginners or those who don't use Outlook too much (or frequently clean-up their mailbox).
