Manually Transfer MSG to Yahoo Mail

Users cannot directly import the MSG files into a Yahoo Mail account. In this approach, we will use both Microsoft Outlook and Thunderbird email clients. We will first convert MSG to EML format. Then, we will add a Thunderbird account to Yahoo Mail via an IMAP protocol.

Follow the step-by-step process to begin the import process:

  1. First, launch the Outlook application on your desktop/PC.
  2. Now, browse and open the required MSG file to import.
  3. After that, export the MSG files as EML format locally.
  4. Open Thunderbird and navigate to Account Settings.
  5. Click on Add Mail Account and sign in to your Yahoo Mail email account.
  6. Next, install ImportExportTools NG and create a local folder in Thunderbird.
  7. Import the EML files into this new local folder.
  8. Once imported, drag and drop emails from the local folder to the Yahoo Mail account folder.

Limitations: This approach is impractical when importing MSG files into a Yahoo email account. The metadata, folder structure, and formatting are not preserved. Also, the complex or large attachments may fail to import.
