Here, we copy the selected emails instead of deleting them from Thunderbird.<\/p>\n Part 1: Adding Your Outlook account to Thunderbird<\/span><\/strong><\/p>\n\n- Access<\/span> Thunderbird<\/span><\/strong><\/li>\n
- Go to the Navigation Section<\/span><\/strong> and then <\/span>Account Settings<\/span><\/strong>.
![\"Click](\"https:\/\/www.viceversatools.com\/blog\/wp-content\/uploads\/2026\/10\/account-setting-300x163.png\") <\/span><\/li>\n- Press<\/span> Account Actions <\/span><\/strong>and choose <\/span>Add Mail Account.
![\"Click](\"https:\/\/www.viceversatools.com\/blog\/wp-content\/uploads\/2026\/10\/add-account-248x300.png\") <\/span><\/strong><\/li>\n- In the new window, provide the target<\/span> Outlook email address and password, <\/span><\/strong>then click <\/span>Continue.
![\"Add](\"https:\/\/www.viceversatools.com\/blog\/wp-content\/uploads\/2026\/10\/outlook-300x234.png\") <\/span><\/strong><\/li>\n- Now wait for Thunderbird <\/span>to automatically locate the correct Outlook\/Microsoft server settings<\/span>.<\/span> Then click<\/span> Done.<\/span><\/strong><\/li>\n
- A Microsoft sign-in window may appear; provide your Outlook credentials and press <\/span>Allow\/Accept<\/span><\/strong>.<\/span><\/li>\n<\/ol>\n
Part 2: Confirm Whether Outlook is Added<\/span><\/strong><\/p>\nOnce the setup is finished, check the left side of Thunderbird to see the listed Outlook account. You can click that account to view all its folders.<\/p>\n Part 3: Locate the Target Emails<\/span><\/strong><\/p>\nNow search for the emails you want to export in Thunderbird.<\/span><\/p>\nPart 4: Select the emails<\/span><\/strong><\/p>\nIf you want to export a single email, select it. If you want to transfer multiple emails, hold Ctrl on your keyboard and click the other emails you want. To export all emails in a folder, select an email and then press <\/span>Ctrl + A.<\/span><\/strong><\/p>\nPart 5: Now, Copy Them to Outlook<\/span><\/strong><\/p>\nRight-click and select Copy To.<\/p>\n Part 6: Wait to Start the Transfer Process<\/span><\/strong><\/p>\nThis part can take time depending on how many emails you want to export. Don\u2019t turn off Thunderbird at this time.<\/span><\/p>\nPart 7: Assess Transferred Data<\/span><\/strong><\/p>\n\n- Now, <\/span>it\u2019s time to access the<\/span> Outlook <\/span>Account<\/span> in your web browser and sign in to your <\/span>Outlook<\/span> account.<\/span><\/li>\n
- Check the Inbox to evaluate the transferred data.<\/span><\/li>\n<\/ul>\n
Part 8: Don\u2019t Delete the Exported Emails Immediately from Thunderbird<\/span><\/strong><\/p>\nIt<\/span> is an important step; here you check the <\/span>email quantity<\/span>.<\/span> Suppose you exported 500 emails; the Outlook account should have 500 new emails with all their properties intact.<\/span><\/p>\n<\/span>Technique 2: Migrate Thunderbird Emails to MS Outlook Using EML<\/span><\/h3>\nThis is a simple process. For this, you save emails from Thunderbird in EML and then import EML files into Outlook.<\/p>\n Part 1: Export Thunderbird emails as EML files<\/span><\/strong><\/p>\n\n- Access Thunderbird on your system and navigate to the target folder, such as Inbox.<\/span><\/li>\n
- Select a single email or hold Ctrl to select multiple emails, or press Ctrl + A to select all emails.<\/span><\/li>\n
- Right-click the selected emails, choose <\/span>Save As<\/span><\/strong>, and select <\/span>File<\/span><\/strong> (or choose <\/span>Save Selected Messages, EML Format<\/span><\/strong> if using the native menu\/add-on) to save them locally.<\/span><\/li>\n<\/ul>\n
Part 2: Organise your EML files<\/span><\/strong><\/p>\nSince the EML format <\/span>carries<\/span> a single email, <\/span>creating<\/span> a separate folder to organise these EML files <\/span>is a good idea<\/span>.<\/span> You can create<\/span> separate folders for each mailbox. This practice will make organisation easy.<\/span><\/p>\nPart 3: Open Microsoft Outlook<\/span><\/strong><\/p>\nO<\/span>pen the Microsoft Outlook desktop application on your computer.<\/span><\/p>\nPart 4: Importing EML into Outlook<\/span><\/strong><\/p>\nRemember, EML <\/span>to<\/span> Outlook <\/span>import<\/span> can vary.<\/span> It mainly depends on which Outlook application you are using. <\/span><\/p>\nFor Classic Outlook, the import process includes:<\/span><\/p>\n\n- Access the folder containing EML files in Outlook. <\/span><\/li>\n
- Select or double-click an .eml file to open it.<\/span><\/li>\n
- Copy the message to the desired folder in Outlook.<\/span><\/li>\n
- Follow the same<\/span> process for each email <\/span>that<\/span> you want to save in Outlook.<\/span><\/li>\n<\/ul>\n
