Microsoft Outlook is one of the most widely used email clients, both in personal and professional settings. While Outlook offers a range of features, sometimes you need to save an email as a file for easy access, sharing, or archiving. One of the most common formats for saving Outlook emails is the .msg file format. However, on a Mac, saving emails in the .msg format is not as straightforward as it is on a Windows PC. Fortunately, there are several methods you can use to save Outlook email as MSG on Mac.

In this guide, we’ll walk you through the process step by step, helping you to save your Outlook emails efficiently as .msg files on your Mac.

What is an MSG File Format?

The .MSG file format is a proprietary email file format used by Microsoft Outlook and Exchange to store individual email messages, including the content, attachments, sender/recipient information, and other metadata. The format is designed to store all the relevant data associated with a single email in a single, self-contained file.

Why Save Emails from Outlook as MSG Files?

Single Email Message: The .msg format stores a single email message, including all attachments and metadata, which makes it a perfect choice when you want to preserve the complete integrity of the email. This ensures that your email content remains intact without any additional or unnecessary data.

Easy Sharing and Transfer: Saving an email as a .msg file allows you to easily share or transfer a single email without exposing other email content, such as the entire conversation thread. This is particularly useful when you want to keep your data private and only share the necessary part of your communication.

Small File Size: MSG files are relatively small in size, making it easy to carry multiple MSG files without taking up too much storage space. This can be especially useful for archiving large numbers of emails while keeping your files manageable.
