What Are MSG Files?

MSG is an email file format associated with Microsoft Outlook. It stores an individual email and its related information, such as To, From, Cc, Subject, message body, and attachments.

• Install or open a desktop email client that can access your Microsoft 365 mailbox and open the MSG messages.
