There are several ways to easily convert Thunderbird to Outlook account, but the right method depends on factors like your technical skill level, mailbox size, and specific needs. Below are two free manual methods you can try to move your emails yourself:
Method 1: Using a Gmail Account as a Bridge
Start by adding your Gmail account to Thunderbird with IMAP. Create a new folder in Gmail and copy the emails you want to move into this folder. Then, add the same Gmail account to Outlook. Once it syncs, your copied emails will appear in Outlook, where you can drag them to your preferred folder.
Method 2: Drag and Drop
Open Thunderbird, select the emails you’d like to export, and save them as .EML files to your computer. Next, open Outlook, create a new folder (or choose an existing one), and drag these .EML files into it. Your emails will now be available in Outlook.
While both methods are free, they can be slow for large mailboxes.
For a faster, simpler option, consider the BitRecover Thunderbird Converter Software. This professional tool easily converts entire mailboxes at once, offers bulk and selective conversion, and has a user-friendly interface. It doesn’t require Thunderbird or any extra software and works on Windows and Mac. The free demo lets you convert 25 emails to test it, while the full version removes all limits for a smooth migration to Outlook.
