This complete guide will help you learn about the importance of MSG conversion, the risks of converting emails from MSG format to another format, various methods of converting MSG emails manually, and how to safely preserve your email data during conversion using the professional tool.

Understanding MSG Files and Their Importance

MSG is an email format developed by Microsoft for Outlook to keep track of each complete email message. It contains information about:

  • Beginning and Ending points (Sender and Recipient information)
  • Your Subject and Body
  • Any Attachments you may have
  • The date and time the email was sent
  • The formatting and other characteristics of the email (metadata).

Many people use MSG files for Email backups, legal documents, and to archive emails; however, they are only compatible with Outlook, so you'll need to convert them for use in other email systems and apps.

Why Preserving Email Data During Conversion Matters

When converting from one format to another (e.g. MSG to PST, MSG to EML, and so forth), it is very important to maintain the integrity of the original email message. Neglecting this could result in:

  • The attachment being missing
  • The message header not being present
  • The email having no formatting
  • The contents of the email being garbled
  • The metadata being lost.

The above items help to ensure that the electronic records of an email are complete, accurate, and legally valid.

Common Formats Used for MSG Conversion

There are several options for conversion of MSG files. These include:

  • PST files (Outlook Data Files)

These files allow users to import their emails into Microsoft Outlook and allow users to move data to other Outlook accounts.

  • EML files

These files are supported by many different email clients like Thunderbird, Windows Mail, and Apple Mail.

  • MBOX files

These files are utilized by many different email applications, including Thunderbird and various cloud-based email systems.

  • PDF files

These files are useful for printing, sharing securely, and serving as legal documents.

These files are helpful for viewing on the web, archiving and providing access.
