Ways to migrate emails from Thunderbird to Office 365

There are manual way and professional tools, two ways are available to migrate emails from Mozilla Thunderbird to Office 365. Here we are explaining one manual way and one professional tool. Begin with the manual method.

Import Files from Thunderbird to Office 365 using the manual method

Firstly Office 365 doesn’t support the MBOX file, so you cannot migrate the MBOX file directly to Office 365. To migrate the MBOX file from Thunderbird to Office 365, users have to convert all data into a supportive format such as EML and PST.

The manual method has two phases. In the first phase, you have to migrate MBOX file data to PST file format, and then convert the PST file into Office 365. Let’s discuss those briefly:

Convert the MBOX file from Thunderbird to Outlook

At first, create a new folder on your system.
Launch Thunderbird, open the folder where the emails are stored, which you want to migrate.
Choose the emails and then click on Save as, an option from the menu.
Browse the folder (Created on the first step) save the e-mails on it.

Import e-mails from Outlook to Office 365

Open the Outlook application on your system.
Browse the folder where you want to save the Thunderbird emails, or you can create a new folder. (make a click on the folder tab. After that, choose the new folder option, and create a new folder)
Now, click on the Ok button. The folder you have created will be shown on the left side of the email application.
Now, click on the folder to view/open its content at the center panel.
At last, drag all the emails from the desktop folder to this folder in Outlook.

This is how you can convert MBOX files from Thunderbird to Office 365. But the manual method has some drawbacks and limitations too.

Drawbacks of manual methods

The manual method has restrictions on the number of emails migrated. Hence, users can only migrate a few mails in a single go. If any user has many emails to migrate, then it has to repeat the same process again and again.
The manual method is time-consuming and complex. Non-technical users and beginners cannot pursue a manual way without any technical assistance and knowledge.
In the manual method, there is no guarantee of successful migration. Besides this, the manual method is not able to keep the data integrity and folder hierarchy maintained. Usually, in the manual method mail formatting and SMTP header are changed for a few emails of Thunderbird.
In the manual method, there are high chances of data loss as well as human error. A little misstep and all your data will become trash.
