Instructions on Copying Emails

Once you have followed the steps above, you may move on to the following steps to copy your emails to your configured secondary email.

  1. Create a folder in the secondary email configured to the Thunderbird email client by right-clicking on your secondary email's "Inbox" and selecting "New Folder" and name the folder. This will serve as the folder where all your emails will be stored within your secondary email account.

  2. To copy an email into the folder you created, highlight the email, right-click, and select "Copy To" and select the folder you created in Step 1. The email should now be copied to your newly created folder.

    Note: Thunderbird allows to copy sub-folders to secondary emails by following the same right-click & select "Copy To" workflow described in Step 2. This does not work for primary folders such as "Inbox", "Sent Items", "Deleted Items", and "Junk Mail". If you are intending on copying all the emails within those primary folders, it is recommended to use the "Select All" keyboard shortcut, CTRL + A. Then you may right-click and select "Copy To" to move multiple emails at once.

  3. To verify that the email successfully copied to your secondary email, log in to your secondary email through a web browser to confirm that the email is in the folder location that you copied the email to within Thunderbird.
