You will find all the information about this tool and about this task of converting the related email files below.
Brief Explanation of OST and EML and the fundamentals of email conversion!
EML | OST |
EML is an abbreviation for ‘Electronic Mail’ and is one of the oldest and most used formats for storing email messages. It is created to comply with industry standard RFC 5322, which makes it compatible with many email clients, other types of applications, and even servers. Which is also why many email users like to keep their backup data in EML, so they can use the file in future even if they have switched their email clients. It used by many clients, including Windows Live Mail. | OST is in the same family of file formats as Outlook native file PST in Windows. It is an abbreviation for ‘Offline Storage File’ and is used in Windows Outlook to store your email messages locally. It is basically a copy of your server data and is synchronized both ways to make working offline convenient. But the file itself cannot be used manually by users for purposes like migration, import/export, etc. |
As it is clear from the above explanation of OST file, the reason you need a designated program is because OST file cannot be used any other way.
These converters can extract the emails and all the supplementary information and embed all of it in an appropriate format (EML, in this case). Even within Outlook itself, you cannot use OST file other than the default internal function of Outlook, which automatically works with the original email account. If you suppose your account is deleted but you have the OST file associated with it (it does happen quite often due to sudden interruptions or corruption of data), you will not be able to simply open OST in Outlook.
For those cases, you have to convert OST to PST and then import PST back into the client. For moving database into Live Mail, you have to do the same, except convert OST to EML files.
Converting OST to Windows Live Mail Can be Bitter!
Email migration may sound simple in theory – simply convert files from the original/input format into whatever format you need depending on the email client of your destination. But it can get quite messy and the process of converting the files can get quite elaborated and time consuming. This is due to the differences in the internal structure of the files and their syntax. A simple file converter without actual restructuring of data won’t work.
The problems seen the most of the times are:
- It takes too long to extract and reimplement the data from OST to EML
- The process requires multiple manual inputs and configuration settings that can be overwhelming
- Non-user-friendly interface and control panel without proper instructions
- Lack of options to let users adjust the results and the files the way they want
- Loss of information and details during the process
- Mismatch between input and output files in terms of metadata and structure
- Integrity damage
- Lack of support in either proper documentation, help, or a support team
