Stellar applications have always been on the top when it comes to Exchange migration software, they seem to be on the top of the market and leading technology. Stellar Converter for EDB makes it easy to open mailbox databases of any size and from any version of Exchange Server, without an Exchange server installed.

The Conversion Process

After you open the application, you will be asked what type of database you will open. If you select Hosted Exchange option then you can export Hosted Exchange Mailboxes to PST, EML, MSG, RTF, PDF, and HTML formats.

  • In this case, since we are migrating from an offline EDB, we use the right option.

  • Either Browse for the EDB files or use the Find button.

  • Here, the application will scan the EDB file, and you will be presented with a full interface to browse through your data stores.


Converting EDB to PST

After selecting the mailboxes and folders to export, you need to click on the Save button as below.

Select the option Save as PST and click Next. Select the destination for the exports and click Next.


Migrating Data from a Local Exchange Server to Office 365

As we did with the PST format, in the Save button window, we need to select Export to Office 365 and enter the details of the destination tenant. After this, we can select the mailboxes and their mappings.

Afterward, we can just check the progress of the migration of data.


Performance and Reliability

The application’s performance was quite fast when it comes to the export of data. Of course, when migrating huge amounts of data to Office 365, you need to compensate the local machine with RAM and CPU depending on the size of the EDB file and you need to factor in the capping of the Office 365 tenant along with the bandwidth of your internet connection.


Pricing and Licensing

The application comes into three options the Corporate limited to 50 mailboxes, the Corporate with 100 mailboxes, and the Toolkit with unlimited mailboxes and a bundle of applications.

Corporate license 1 costs $299 which includes the extraction of 50 mailboxes with all the application features. Corporate license 2 costs $399 and it is the same as its predecessor, but it has a limit of 500 mailboxes.

The Toolkit is the grand license where it allows an unlimited number of mailboxes, along with a bundle of applications included in the price of $699 as below.

  • Repair Exchange Server Database
  • Convert OST to PST
  • Extract Mailbox from Exchange Backup
  • Recover the Password of Microsoft Exchange


Pros and Cons

As said above, the application is great to work with. You can get started in minutes and the features are great. The simplicity of the interface and non-complex mechanisms make working with the application a breeze, and you don’t need a big technical background to work with. Its compatibility with any Exchange Server, no size limits, and ability to migrate anything to Office 365 and vice versa is great!

The only con we can find is the lack of a split option, which is an important feature when migrating large mailboxes to PST.



As we have seen, the application is clearly that it’s one of the leading companion apps for any Exchange Server. It’s easy to install and use. You can migrate to a live Exchange Server database and here, we have seen how to migrate to Office 365. It’s a great application to work with and its simplicity and great features will surely lower the costs of the migration and data consistency assurance.
