Can I open MSG files without Microsoft Outlook?
Yes. ViewAnyFile.app opens Outlook .msg files in your browser without any Outlook license. The viewer renders the full message, headers, and attachment list.
What is the difference between EML and MSG?
EML is the open RFC 5322 format used by most email clients. MSG is Microsoft's proprietary binary email format used specifically by Outlook. Both are supported by ViewAnyFile.app.
Does the MSG viewer show attachments?
Yes. All attachments embedded in the MSG file are listed with their filenames. Supported attachment types (images, PDFs, text) can be previewed directly.
Why can't Windows open MSG files natively?
MSG is a proprietary Microsoft format that requires Outlook or a compatible application to parse. ViewAnyFile.app uses a JavaScript MSG parser to decode the binary format directly in your browser.
