  • There should be enough storage space available in the Outlook you are using.
  • The EML files should not be too large in size.

How to Convert EML to MSG Using Manual Approach?

Use Outlook New to save EML as an MSG file. For this, import the EML file using Outlook New’s built-in feature. Once done, export them at the desired location using the Save As MSG option. The detailed steps for the same are as follows:

  1. Open Outlook New on your device.
  2. Then, click on the Settings icon from the top-right section.
  3. In the opened window, click on Data Files from the left panel.
  4. Now, from the given options, choose Import and click on the Start Import button.
  5. Next, select the folder that has EML files and click on Upload.
  6. Once the upload completes, click on the imported EML file in Outlook New that you want to convert to MSG.
  7. After this, click on the three-dot menu icon and select the Save As option.
  8. From the given options, choose MSG.
  9. Finally, select the saving path and click on Save to convert EML to MSG format.

Drawbacks:

It does not allow random selection of EML files to import. Hence, all the EML files should be saved locally in a dedicated folder.

Users can only import 25 MB of files in Outlook New using the built-in option.

It only supports EML files from the top level in the folder. If the EML files are saved in sub-labels or have a multiple-folder tree, then those EML files would not import in Outlook New.

The process is very slow and will cancel if, knowingly or unknowingly, Outlook New closes.

The user has to save each EML to MSG one by one, as there are no bulk or automation options available.

Does not support attachments, formatting, and the original folder hierarchy of the email file.

This is not a standalone solution, which puts the data at risk.
