How to open .EML files on Android
To open .EML files on Android, open the .eml from your Downloads/Files app; if it only shows raw text or won’t open, share/transfer it to a desktop email client or a dedicated mail viewer app you trust.
Step-by-step instructions
- Open the .eml from your Downloads/Files app; if it only shows raw text or won’t open, share/transfer it to a desktop email client or a dedicated mail viewer app you trust.
Common issues
The .EML file opens as unreadable raw text
This typically happens when the file is opened in a plain text editor that does not interpret RFC 5322 headers and MIME parts (HTML body, attachments).
- Open the .eml with an email client/viewer instead of a text editor.
- If you must inspect it manually, use a text editor only to verify headers, and extract attachments using a mail client that understands MIME.
Double-click opens the .EML in the wrong program
File associations may be set incorrectly (for example, not associated with message/rfc822 or mapped to a generic editor).
- On Windows: right-click → Open with → choose Outlook (or another mail client), and set it as the default for .eml if offered.
- On Linux: change the default application for message/rfc822 or the *.eml association via your desktop environment settings (shared MIME-info).
Outlook won’t open the .EML as expected
Different Outlook versions and configurations (including the new Outlook) can behave differently when opening .eml files.
- Use Microsoft’s documented method for opening .eml in the new Outlook (see Further reading).
- If one method fails (e.g., double-click), try opening from within Outlook or using Open with from File Explorer.
Attachments are missing or won’t open
The .eml may be incomplete/corrupted, or the message’s MIME structure may not have been preserved during download/transfer.
- Re-download or re-export the .eml from the original source to ensure the full message is saved.
- Open the .eml in a mail client that supports MIME so attachments are recognized and extracted correctly.
Security note
.EML files can contain links, HTML content, and attachments via MIME; treat them like opening an email—be cautious with unexpected senders and do not open attachments you don’t trust.
