PLEASE NOTE: Lehigh does not support using Thunderbird to access your Gmail account for day-to-day use. This document is provided ONLY as a means of moving your Thunderbird Local folders up to the Lehigh Gmail account.
Some people store email messages locally, on the computer hard drive. In Thunderbird these folders are listed below the Lehigh account, under the heading "Local Folders." Depending on the number of folders, this process could take several hours or even longer. We advise migrating only those folders that you want to preserve for future use.
Before you begin, you will need:
- Your Gmail passphrase (not your password, but a separate credential for purposes of moving mail only). If you don't already have it, use this link to Lookup your Google Passphrase.
- These instructions.
- A good Internet connection.
Make sure your version of Thunderbird is up-to-date. If you're not sure, go to https://www.mozilla.org/en-US/thunderbird/ and download the installer. Once it's finished downloading, run the installer and follow all the on-screen instructions. Now you're ready to proceed.
Make sure all the server settings match the screenshot to the right. For reference, they are:
- Incoming : IMAP : imap.gmail.com : Port 993 : SSL/TLS : Normal password
- Outgoing : SMTP : smtp.gmail.com : Port 587 : STARTTLS : Normal password
- Username :
Click the Re-test button to confirm that there are no problems with your passphrase or server settings. Now click the Done button. Back in the main Account Settings screen, click OK to return to the mail window.
You can now begin copying folders from Local Mail to the server. Drag each folder, one at a time, to the Lehigh Gmail account. If you encounter a duplicate folder name, first select all the messages in the local folder, then drag them to the corresponding folder on the Gmail server.
You are done! You can remove Thunderbird if you wish, or if you're continuing to use it for other email accounts or to access Local folders you chose not to move, then you're free to keep it around.
