Quickly learn the simple ways for effortless OST to PST conversion from this comprehensive review of Stellar Converter for OST:

If you’ve used Microsoft Outlook, you are probably aware that it stores its mailbox data in OST format. An OST file keeps all mailbox data on local storage, thus allowing for its use offline. While this is beneficial, the problem arises if such offline data gets corrupted and becomes inaccessible.

Furthermore, as OST files are linked to the profile in which they were created, it would be impossible to import this data to another profile directly. The only way to resolve these issues is to convert the OST file into PST (Personal Storage Table).

There are a plethora of tools out there that do an excellent job of converting an OST file to its PST counterpart in a simple manner.

When testing the tool, I laid special emphasis on its overall utility, functionality, and user-friendliness. I would like to share my experiences on all three elements. We will see how to use Stellar Converter for OST, starting with Stellar’s User-Interface.

User Interface

The User Interface

The interface of Stellar was so impressive that it left a lasting impression on me. One thing you’ll immediately realize when you land on Stellar’s interface is how functionality-focused it is.

You are asked to choose the OST file to convert straight away. The instructions are presented to you from the beginning. All you have to do is follow them.

The UI is immaculate. All the features you need are just a click away. It has that simple look that also accommodates sophistication. In essence, I was happy with the interface. The functions were not confusing at all and I don’t think you’ll need to be a tech wizard to use this software.

Features

As I mentioned before, Stellar is known for its features. It can do a lot more than just convert OST to a PST file format. Here are all the features it offers and my thoughts on each one of them:

#1) OST to PST Conversion

Let’s start by first taking a look at its primary feature. Stellar makes the process of converting OST to PST files very simple. It is incredible at converting large-sized OST files at exceptional speed. Extracting mailbox data from OST files for conversion does not mess with the original folder hierarchy, attachments, or email formatting.

This, in my opinion, is what makes Stellar Converter for OST a cut above the rest. It can convert and extract mailbox data with 100% precision and accuracy. The tool supports OST files that have been created by almost all versions of Outlook.

The conversion process itself is also very simple.

Here’s a step-by-step guide to how Stellar performs OST to PST conversion:

1. As soon as you launch the software, you’ll be greeted with a choice. Click the ‘Browse’ button if you know where your OST file is located. On the other hand, click the ‘Find’ button to auto-locate the file you wish to convert.

2. Select the OST file you wish to convert and hit the ‘Convert’ button.

Besides PST, you are also provided with multiple file format conversion options. You can convert your OST file into MSG, EML, RTF, HTML, and PDF format using the same steps.

#2) Precisely Extract all Offline Outlook Data

Another thing that Stellar does well is extract all data from an OST. This includes emails, contacts, attachments, journals, notes, etc. It maintains the integrity of mailbox items during the extraction/conversion process.

This makes the tool perfect for OST file extraction or conversion, especially when an outlook profile is not there.

The tool also does a commendable of sorting and organizing OST file data that’s extracted. Once the scan is complete, you are allowed to sort or organize emails by Subject, Date, Type, Attachment, Importance, To, From, etc.

#3) Auto Locating an OST File

Stellar is a useful tool especially if you have no idea where your OST files are located. As you already know, Stellar presents you with two options to initiate the OST conversion.

One of those options is to auto-locate an OST file to convert. If you don’t know where your OST file is located on the system, you can rely on the software to locate and list the files on your behalf from the default location. Or you can also select OST file manually if you know the location.

#4) Preview Offline Outlook Data File

Preview Offline Outlook Data File

The software presents you with a detailed preview of every item stored in the converted OST files. You can view its content by simply clicking on the mailbox item, which could be anything from an email and calendar to a folder.

This feature is quite useful if you wish to extract certain items from an offline outlook data file.

#5) Finding Individual Mail Items

Let’s say you wish to find specific mail items. You can do so using the ‘Find Message’ button. Once you hit that button, you’ll be taken to the Find Message Window. Here, you can find a particular mail item by using parameters like Subject, Date, Type, Attachment, Importance, To, From, etc.

These items can then be saved in PST, MSG, PDF, HTML, and EML format by simply right-clicking on the chosen mail item.

#6) Save and Load Scanned Files

Stellar allows you to save a scanned file as a DAT to load it later for conversion. To do so, you’ll need to adhere to the following instructions:

  • On the Home Menu, click on the ‘Save Scan Info’.
  • You’ll be taken to the Save Scan Info dialog box. Click the browse button to select the folder where you wish to save the scanned information. You also have the option to create a new directory, which can be used to track a saved DAT file.

  • Click ‘OK’ to save the DAT file.
  • To load the saved DAT file, all you have to do is click the ‘Load Scan’ button on the home menu right beside the Save Scan button.

This is a great feature and stops a user from scanning the same file again and again. It can save you a lot of time, especially when large OST files are involved. With the help of this feature, you can efficiently split the scan and preview process based on your specific requirements.

#7) Auto-Split PST Files

Stellar provides you with an option to split a large PST file with its auto-split feature. You can use this feature to automatically split an oversized PST file. This is another useful feature that can keep your PST files from getting corrupted owing to their large size.

Besides auto-split, Stellar also presents you with the option to split files based on size. You’ll be able to split a PST file in sizes ranging from 1-50 GB while ensuring the original organization of mailbox data isn’t disturbed. This feature is exclusive to the Technician edition of the tool.

#8) Export OST Data to Office 365

Now this is a feature that’s only available to those who have purchased Stellar Converter’s Technician Edition. If you have, then you’ll be able to directly export your OST to PST-converted files to Office 365.

What makes this feature impressive is the fact that you can export the mailboxes from your Office 365 interface once logged in.

#9) Batch Conversion

Stellar Converter is a tool designed keeping user convenience in mind. Nowhere is this fact more apparent than in the tool’s ability to convert multiple OST files to PST, simultaneously. The software allows you to take multiple OST files and convert them into a PST via a single batch process.

This only makes the conversion process less tedious, especially when you have to extract data from multiple OST files.

#10) Compacts PST File

This is yet another feature that’s exclusive to the Technician Edition. You can compress a large PST file. This feature can save attachments from your PST file in a different folder while ensuring the interlinks throughout your PST file remain preserved. This feature can also help you save all attachments in a completely new PST file.

Customer Support

The technical support provided by Stellar is pretty decent. You have the option to raise a ticket or directly contact the team via phone or live chat. There is a comprehensive user manual, FAQs, knowledge base, and tutorials available for self-support as well.

Price

Price - Stellar Converter

Stellar Converter offers three versions of its tool. The Corporate Version will cost you $79 for a 1 year license. You’ll be able to convert OST to PST and extract all mailbox items with this version.
