OAuth 2.0 AUTHENTICATION

When using Microsoft365, Exchange Online, etc. to send e-mails from this machine, it is recommended to use the OAuth 2.0 authentication method.
This section describes how to operate OAuth 2.0 authentication.

GETTING A TOKEN

With OAuth 2.0 authentication, the service provider provides an access token that can be obtained by the machine to send and receive e-mail.
This section describes how to obtain the token.
The settings should be configured by the administrator of the machine.

When an error occurs during job execution, connect test the POP/SMTP authentication connection in the system settings. If [Token update failed. Please delete the token and obtain it again.] is displayed in the connection test result, delete the token and then obtain the token again.

SMTP Authentication Settings

The following settings are available for SMTP authentication, and the setting method is the same for all cases.

System Settings → Network Settings → Services Settings (SMTP tab)

System Settings → System Control → E-mail Alert and Status → SMTP Settings

System Settings → Network Settings → Quick Settings

System Settings → Initial Installation Settings → Network Quick Settings

This section describes how to obtain a token in System Settings → Network Settings → Services Settings (SMTP tab).

Click "System Settings"→ "Network Settings"→ "Services Settings" → "SMTP" tab in the Web page.

Configure necessary settings such as "Primary Server", "Port Number", "Timeout", "Sender Name", "Sender Address", and "Enable SSL/TLS" in the SMTP Settings.

Select "OAuth 2.0" as the Authentication Method.

Select a provider.

Enter an account name.

Click the [Get Token] key.

Click the [Get Token] key, then click the [OK] key when a confirmation message appears.
The login page of the selected provider will then be appeared.
Log in and follow the instructions to obtain the token.
When a token is acquired, the "Token" display changes from [Not Retrieved] to [Retrieved].

The following settings are common. When OAuth 2.0 authentication is received for any one of these settings, the settings are updated in concert with each other.

System Settings → Network Settings → Services Settings (SMTP tab)

System Settings → Network Settings → Quick Settings

System Settings → Initial Installation Settings → Network Quick Settings

The following settings are independent. Even if you have OAuth 2.0 authentication in other SMTP authentication settings, OAuth 2.0 authentication must be obtained separately.

System settings → System Control → E-mail Alert and Status → SMTP Settings

POP Authentication Settings

The following settings are available for POP authentication.

System Settings → System Control → E-mail Alert and Status → E-mail Status (Advanced Tab)

Click "System Settings" → "System Control" → "E-mail Alert and Status" → "E-mail Status (Advanced Tab)" in the Web page.

Configure necessary settings such as "POP3 Server", "Port Number", and "Check Interval" in the settings.

Select "OAuth 2.0" as the Authentication Method.

Perform steps 4 to 6 in SMTP Authentication Settings.

DELETE A TOKEN

Delete the tokens that have been set up when using the machine with a new account in Exchange Online, etc., or when the tokens have expired and can no longer be used. The settings should be configured by the administrator. Token deletion can also be configured from the web page.

Click the [Delete] key on each SMTP or POP authentication setting screen to display a confirmation message. Click the [OK] key to delete the token.
When the token is deleted, the "Token" display will change to [Not Retrieved].
