- Built-in OAuth: Most Epson models only support password sign-in for email.
- Auth-Email: works with every Epson that supports SMTP. Your device signs in to Auth-Email with a password, and Auth-Email signs in to Microsoft 365, Outlook or Gmail with OAuth. See our scan to email guide.
- Gmail app password: personal Gmail accounts with 2-Step Verification can create an app password and use it instead of the normal password.
- Microsoft 365 without signing in: direct send (to your own organization only) or an SMTP relay connector (needs a fixed public IP address). Set either up with our Exchange Online PowerShell command builder.
Epson scan to email setup
How to set up – or fix – scan to email on Epson WorkForce, WorkForce Pro, EcoTank and AM-C series devices with Microsoft 365, Outlook.com and Gmail. Menu names vary between models and firmware versions, so look for the closest match.
Scan to email stopped working? Microsoft 365, Outlook.com and Gmail no longer accept a device’s normal email password (and Microsoft is retiring password sign-in for SMTP). Unless your Epson supports OAuth, see the options in step 3.
1. Open the Web Config
Type the printer’s IP address into a web browser and log in as the administrator.
Then go to: Network (or Network Settings) → Email Server → Basic
2. Enter the SMTP settings
The settings are usually called:
| SMTP Server Address | The SMTP server name |
|---|---|
| SMTP Server Port Number | The SMTP port |
| Secure Connection | Choose STARTTLS for port 587, or SSL/TLS for port 465 |
| Authentication Method | Choose SMTP AUTH, and enter the authenticated account and password |
| Sender’s Email Address | The sender address – it must match the account you sign in with |
Enter these values, depending on your email provider:
Microsoft 365 / Outlook – through Auth-Email (recommended)
| SMTP Server Address | outlook.auth-email.com |
|---|---|
| SMTP Server Port Number | 465 (or 587) |
| Secure Connection | SSL/TLS on 465; STARTTLS on 587 |
| Authentication Method | On – your full email address, and the password you set in Auth-Email |
| Sender’s Email Address | The same address you sign in with (or one it has permission to send as) |
Gmail / Google Workspace – through Auth-Email (recommended)
| SMTP Server Address | gmail.auth-email.com |
|---|---|
| SMTP Server Port Number | 465 (or 2525) |
| Secure Connection | SSL/TLS on 465; STARTTLS on 2525 |
| Authentication Method | On – your full email address, and the password you set in Auth-Email |
| Sender’s Email Address | The same address you sign in with (or one it has permission to send as) |
Microsoft 365 – directly (SMTP AUTH)
| SMTP Server Address | smtp.office365.com |
|---|---|
| SMTP Server Port Number | 587 |
| Secure Connection | STARTTLS (TLS 1.2 or later) |
| Authentication Method | On – the mailbox address and password. SMTP AUTH must be enabled for the mailbox, and Microsoft is retiring password sign-in |
| Sender’s Email Address | The same address you sign in with (or one it has permission to send as) |
Gmail – directly (app password)
| SMTP Server Address | smtp.gmail.com |
|---|---|
| SMTP Server Port Number | 587 (or 465) |
| Secure Connection | STARTTLS on 587; SSL/TLS on 465 |
| Authentication Method | On – your full Gmail address, and an app password (needs 2-Step Verification) |
| Sender’s Email Address | The same address you sign in with (or one it has permission to send as) |
Auth-Email’s servers for other providers – and legacy servers for devices that only support older TLS versions – are listed in our server settings guide. Older devices that can’t use TLS 1.2 can’t connect to Microsoft 365 or Gmail directly at all.
3. Choose how the Epson signs in
Troubleshooting Epson scan to email
| Connection test failed / Authentication error | The printer couldn’t connect to or sign in to the email server. |
|---|
- Use Email Server → Connection Test after saving the settings.
- Devices often show a vague error. To see exactly what the Epson sends, point it at our SMTP connection tester – it shows the encryption, TLS version and sign-in method the device uses.
- Check the email provider’s server with our email server checker, and look up the server’s error in our error code lookup – for example 535 5.7.139 (Microsoft), 421 4.7.66 (old TLS versions) or 534-5.7.9 (Gmail).
- Use a dedicated mailbox for the device (for example, [email protected]), so that a password change or a staff member leaving can’t break scanning.

Auth-Email works with any Epson printer, scanner or copier that supports SMTP. Authorize your Microsoft 365, Outlook or Gmail account once, then change the SMTP server on the device – no firmware updates or IT changes needed.
Frequently asked questions
Why did scan to email stop working?
Most printers and scanners sign in to email with a username and password. Microsoft 365, Outlook.com and Gmail have switched off (or are switching off) password sign-in, so the device’s sign-in is rejected – usually with an error such as 535 5.7.139 or 534-5.7.9.
Which SMTP settings should my printer use for Microsoft 365?
smtp.office365.com, port 587, with STARTTLS (TLS) and SMTP authentication – but this requires password sign-in for SMTP, which Microsoft is retiring. Alternatives are direct send, an SMTP relay connector, the device’s own OAuth support (if it has it), or Auth-Email.
Do I need a separate mailbox for my scanner?
It’s a good idea. A dedicated mailbox (for example, [email protected]) means a staff member’s password change can’t break scanning, and makes it easy to see what the device sends.
