Bulk export

This is an interesting feature but it is not present in the personal license, it consists in to create a CSV file with the credentials and the file with the PST that you want to import, you will see the Bulk export function the top bar of the interface, for more information you can visit the official website:

Impersonate Export

This feature allows you to import multiples PST with few clicks, but it does not come with the personal license. The process is to create CSV file similar to the Bulk export, but the file only has to contain the PST path and the email address, like the Bulk export you will found this function in the top bar and it will ask for the password of your Office 365 account later, if you are interested to know how it works you can visit the official website:

This is an example of how to import a PST file to Office 365.

Click on add file, we are going to open the PST file.

Select the PST file on your computer.


Once the PST is imported you can see the content in the application.


Select all the emails that you want to export.

The tool is very easy to use, I like email previewer, it doesn't have options is mostly action buttons, but this tool does the work that is the most important part, you can get all the content from a PST file directly to your Microsoft Office 365 account. The time to move the content to Office 365 will depend on some factors like the number of messages and files that the PST has and the internet speed. The price of the software is $99 and it is only for Windows.

My rating of this software is 8 out of 10.
