Stellar Converter for OST- The Perfect OST to PST Converter

MS Outlook creates Offline Outlook Data File (.OST) for IMAP and MAPI accounts. This file serves as a cache of the mailbox on the server and allows the users to access their emails and perform certain actions even when Internet connection is unavailable. These actions include write emails, read emails, search emails, etc.

One important aspect of OST files is that they are encrypted and linked to the email account in which they are originally created. So, if an OST’s connectivity with the mail server, such as the Exchange Server is lost, then you can’t access the file. To open an Offline Storage Table (OST) without its Outlook profile, you need to use an advanced OST to PST converter software. One such powerful tool is Stellar Converter for OST. In this post, I will be reviewing this OST to PST converter tool, based on its functionality, features, and ease-of-use.

Stellar Converter for OST and its Working 

Stellar Converter for OST is a specialized software that converts orphaned OST files into PST and other formats, such as HTML, PDF, RTF, MSG, EML, etc. This powerful utility comes packed with many useful features. I will elaborate each of these features while explaining how to use the software. 

Note: The software comes in three variants – Corporate, Technician, and Toolkit. In this review, I have evaluated the Corporate variant of the software. Technician and Toolkit editions have all the features of Corporate edition, along with additional features such as option to direct OST export to Office 365, Outlook profile or Exchange Server, batch conversion of OST files, etc.

System Used for Testing:

  • OS: Windows 10
  • Storage: Hard Disk Drive
  • RAM: 4 GB
  • Processor: Intel i3, 7th Gen

I downloaded the software and installed it on my system which took no more than a minute or two. When I launched the software, it displayed the following interface:

I was impressed by how neat and organized the interface is. To begin with the conversion process, I clicked the Browse button and provided the path to the OST file I wanted to convert. 

I also tested the Find feature which automatically located the OST files on my hard drive partition. It worked perfectly and even found OST files stored inside the Recycle Bin. Once it finished scanning the C drive, it displayed a pop-up message with the number of OST files (10, in my case) found.

I initiated the file conversion process by selecting the desired OST and clicking the Convert button. 

The software displayed a status window in which I could track the progress of file conversion. Once it was done converting the file, it displayed a Conversion Complete alert box. All the contents of the OST file were neatly displayed for my review (refer to the image below).

The software also recovered the deleted items stored in the OST file and marked them in red color. Messages that contain attachments are denoted by paper clip icons. These small details make it easy to identify the emails. 

There is also a Find Message feature in the software which can help in finding specific emails based on the email address of sender, receiver, subject, etc. I searched for the emails sent to “sabastian” and the software found 12 emails.

There is a date filter to find specific emails, sent or received on a particular date. It also offers an option to save the identified emails in MSG, EML, RTF, HTML, or PDF format by right-clicking the desired emails. 

I closed the Find Message window and previewed the emails in the main window. I could inspect all emails in detail in the right pane where I could see attachments, message body, and email header fields, such as Subject, To, From, etc. I selected the folders that I wanted to convert to PST and clicked Save Converted File button on top. Then another window opened in which I could choose the desired file format for saving the data.

There was a Do not recover Deleted Items option which helps in saving only the primary data (undeleted messages) in the OST file. I selected the option and provided a location for saving the data (I selected PST file format). When I clicked OK, it displayed another window in which I could track the progress of file saving.

When the software saved the file on my system, it displayed an alert message. 

The message displayed the location of saved file and converted file size. There was a link to a guide on “How to import PST file”. This guide is helpful to users who don’t know how to import the converted PST file into Outlook. 

Those who need the details of the conversion process, can go to View > Log Report. This will open a detailed log window which contains details, such as item type, attachments, description, status, etc. (see the image below). 

There is also a Save Scan feature in the software that’s useful in converting large OST files.

This feature allows to save the OST file’s scan data on the system in a DAT file to load it later for conversion.  

Overall, using the software was easy. I had no troubles finding the desired controls and functions in the software. I converted my OST file without a hitch. 

System Requirements

Processor: Intel-compatible (x86, x64)

Operating System: Windows 10, 8.1, 8, 7

Memory: 4 GB minimum (8 GB recommended)

Hard Disk: 250 MB for installation files

Verdict

The software is highly refined, easy-to-use, and offers ample features to perform selective OST conversion. Additionally, a free demo version of the software is also available which can be used for hands-on experience. 

I would strongly recommend Stellar Converter for OST, who is looking for an easy solution to convert OST file to PST file format.
