Frequently asked questions
- Do I need Outlook to open a MSG file?
- No — this viewer decodes the file's binary container format directly in your browser.
- Can I download attachments from a MSG file?
- Yes, each attachment is listed below the message body with its own download button.
- Is my message uploaded anywhere?
- No, decoding happens entirely client-side.
- Will complex formatting look exactly like Outlook?
- Most rich-text formatting renders faithfully; some unusual formatting may render as simplified text.
- Does it support MSG files with embedded messages?
- Basic embedded-message attachments are listed as attachments; deeply nested message threads may not fully unpack.
