Migrate Thunderbird to Betterbird with Existing Thunderbird Profile
Betterbird is designed to directly get Thunderbird data directory when it is installed. So, there is no need for you to manually import the profile. However, if you want to run Betterbird independently with separate profiles, move to a new computer, or if the version path is registered or profile locks prevent automatic detection. Then, follow the steps below.
- Close your Thunderbird completely.
- On your computer, find your Thunderbird profile. By default, the profile path is in Windows: C:\Users\\AppData\Roaming\Thunderbird\. Note down the profile path.
- Download and install Betterbird from the official site. After launching the app, close it immediately.
- Copy your Thunderbird profile directory and paste it to a safe place as a backup.
- Find your Betterbird Profile Directory using the Profile Manager, then launch Betterbird.
- With the same manager, select, map, or link your Thunderbird profile directory.
- Launch Betterbird and check your account, emails, address book, and other data to confirm it is successfully transferred.
Add the Same Email Account in Betterbird
Users can link the same email account that was linked with Thunderbird in Betterbird. It also supports an IMAP server, so configuring the same email account is easier.
- Open the Betterbird application and click the Application Menu button.
- Select New Account and press the Email button.
- Enter your full name, email address, and password. Click the Continue button.
- Select the IMAP option, then log in to your native page. Click the Allow button.
