What is an MSG File?

You see your emails as usual on Microsoft Outlook, however, it stores your emails as MSG files when you export them. But that’s not it. Outlook is not just a mail application. It is also a calendar, contacts database, and task management tool. And it stores every item as an MSG file when exported. So, when you see an MSG file, it could be an email, a task, an appointment, a contact, a calendar entry, or any other saved Outlook item.

If an MSG file is an email, it stores the time, date, sender and receiver’s information, subject, attachments, hyperlinks, and message body along with its format.

(Another program uses MSG files that are completely different from Outlook’s MSGs. That program is a game called Fallout. Both Fallout 1 and 2 use the Fallout Message file format to save its game messages and dialogues.)

What is a PST File on Outlook?

Just as MSG files store single emails or outlook items, the same way PST files (.pst) can save multiples of outlook items. A single MSG file would have only one email, appointment, task, or contact while a single PST file can have emails, tasks, appointments, and contacts. Usually, when you export your Outlook data, your data files are saved in the PST file format.

Is the MSG File Format Safe?

An MSG file itself is not harmful as it’s only a file format to save Outlook items. But the safety of MSG files depends on where they came from and their contents. If you created an MSG file, then it’s completely safe for you. But if you received an MSG file, it could contain any virus or malware. So, it’s much like an email. It could be harmless or risky depending on its contents.

The MSG format is used by Outlook, but if you’re using Outlook for Mac, it doesn’t support MSG files. Instead, you will see your exported emails in the EML (.eml) format. EML is an E-Mail Message format that can be easily opened by Outlook, Thunderbird, and other mail apps on both Mac and Windows.
