Method 2. Copy Thunderbird Profile to Another Place
Thunderbird profile is a folder saving users’ personal information including local emails, messages, address books, contacts, passwords, and preferences. It is located in a separate location from the Thunderbird program files. When you install Thunderbird, it creates a profile called “default”. This profile will be used automatically to save your personal info unless you create a new profile.
Each profile is saved on your hard disk in a profile folder. The folder is named using this convention: <random_string>.<profile_name>. <random_string> is 8 digits randomly generated by Thunderbird and <profile_name> is the name you assigned to the profile.
The location of the profile folder varies from different operating systems, even though you specify a non-default location when you create the profile. In general, the address of the default profile is C:\Users\<username>\AppData\Roaming\Thunderbird\Profiles\xxxxxxxx.default\.
Therefore, to make a copy of the profile is also a way to do Thunderbird backup email. The process of copying the Thunderbird profile to another place is as below.
Step 1. Locate the profile folder of Thunderbird. There are two ways:

The AppData folder is hidden in default, so you need to check Hidden items under the View tab menu in Windows Explorer. Or, you can search “%APPDATA%\Thunderbird\Profiles\” in Windows Run or Windows Search.
Step 2. Close Thunderbird.
Step 3. Go to one level above the target profile’s folder. Usually, it is C:\Users\<username>\AppData\Roaming\Thunderbird\Profiles\. Right-click on the folder and select Copy.
