In this article, we will see how you can convert MSG to MP3/MP4 format. There are multiple ways to convert MSG to MP4 and MP3 audio. Before converting MSG directly into audio or video format, we have to understand that MSG files contain attachments in which audio and video files are present. From there, you can extract your attachments and then convert MSG to MP3 or MP4, either manually or automatically.

So, let’s see how you can extract the attachments and convert MSG to audio and video files using both manual and automated approaches.

Is it Possible to Convert MSG to MP4 and MP3 Directly?

There is no direct manual way to convert MSG to audio or video format. First, extract attachments manually via Outlook and then convert MSG to MP4 or MP3 by using the free online tools. On the other hand, you can use the direct MSG to MP3/MP4 converter, which will extract attachments in bulk and then convert MSG to MP3/MP4 format without any data loss.

The manual way is a risky and time-consuming process, and an automated solution is a dedicated solution for crucial files. Let’s throw light on both the approaches to get a clear picture and the difference between the two.

Free Ways to Extract Attachments and Convert MSG to MP3 or MP4

A. Extract Attachments from MSG files

Go to Outlook and open your MSG files.
Double-click on the MSG files and click on the “save all attachments” option to extract all the attachments in that particular MSG file.

Note: Repeat this process one by one for each file to save your attachments containing audio and video files. You should have Outlook installed and subscribed to perform this approach.

B. Convert MSG to MP4 and MP3

There is no direct way to convert MSG files into MP3/MP4 format. After extracting the files manually, you use the free online tools available in the market.

Why not use the Manual Approach to Extract and Convert MSG to Audio & Video?

In the manual approach, you are only extracting the attachments one by one using Outlook, in which audio and video files are present. But further, converting those files to MP3 or MP4 using a free online tool is not advisable.
Using free online tools is risky as data is uploaded on the internet, and it often leads to errors while exporting MSG into MP3 or MP4 format. The originality of the files gets disturbed.
High risk of data breaches, data loss, corruption, errors, and more. Downloaded files from there may contain hidden malware and trigger browser warnings, which is risky, especially if you are a lawyer, investigator, or a professional who has crucial files to convert.
Also, extracting via Outlook does not maintain the original hierarchy and consumes a lot of time to extract each file one by one.

So, let’s see the best alternative solution to extract and convert MSG to MP3 and MP4 formats easily in bulk without any changes.

Easy Solution to Convert MSG to MP4/MP3 without Data Loss

Instead of using Outlook and free online tools, which are risky and not advisable to use, you can use the BitRecover MSG converter to convert MSG files directly into RTF format, which will save attachments in a separate folder, and from there, you can convert MSG to MP3/MP4 in bulk.
