Good tool, it is fast and accurate. But there is no German GUI, so only 4 stars from me.

 by Francois Bosse
Overall - good

Overall, the programme is good, works faster than its competitors and converts emails correctly. No encoding or attachment errors. Everything is transferred.

The bad thing is that it only converts messages, not contacts. There is another programme that converts contacts. But the good news is that you can buy both at once for a great discount!

It's a must-have tool

As the editor of online magazine, I was impressed by the Thunderbird to Outlook Transfer software.

The Thunderbird to Outlook Transfer software is easy to use, and it offers a user-friendly interface that makes the process of transferring emails a breeze. With just a few clicks, you can transfer all of your Thunderbird emails to Outlook, including attachments, formatting, and metadata.
One of the most impressive features of this software is its speed. The transfer process is lightning-fast, and you can move large volumes of emails in just minutes. This is particularly useful for businesses or individuals who need to transfer a large number of emails quickly. What's more, the Thunderbird to Outlook Transfer software is also very reliable. The software is designed to ensure that your emails are transferred accurately and without any loss of data. This is particularly important for businesses that rely on their email communications to function effectively.
Overall, I would highly recommend the Thunderbird to Outlook Transfer software to anyone looking for a reliable and efficient solution for transferring emails between these two popular email clients. It's a must-have tool for anyone who needs to transfer emails regularly or wants to switch from Thunderbird to Outlook.

This is must have tool for all Thunderbird users. With help of this software I do the regular backups of my TB messages in the PST format. I have Outlook installed but I do not use it by now, however I plan to migrate to it in the nearest future, so I will be ready having all my mail by the hand in the compatible format. Your software is very easy to use and working like a charm!

Very reasonable price!

You did an excellent job of converting my old Thunderbird email to Outlook Email. I was the victim of identity theft and it is only by a miracle that I was able to copy all the thunderbird data to a USB drive as that machine has been compromised. They seem to be able to get in via mail messages in Thunderbird even though I have Thunderbird protected. Very sophisticated thieves, with an insidious scam to get you in contact with them. Now that I have my email back, I can go ahead and delete thunderbird and all its data from the old machine in the hope that will finally end their ability to get onto the system. Thanks again for a great job at a very reasonable price! 😊
