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.
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.
The following settings are available for SMTP authentication,
and the setting method is the same for all cases.
Tap "Settings (Administrator)" → "System Settings"→ "Network Settings"→ "Service Settings" → "SMTP" tab.
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.
Tap the [Get Token] key.
Tap the [Get Token] key, then tap the [OK] key when a confirmation message appears.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.
The following settings are available for POP authentication,
and the setting method is the same for all cases.
Tap "Settings (Administrator)" → "System Settings"→ "Printer Settings"→ "E-mail Print Settings".
Configure necessary settings such as "POP3 Server", "Port Number", "Check Interval", and "Enable SSL/TLS" in the settings.
Select "OAuth 2.0" as the Authentication Method.
Perform steps 4 to 6 in SMTP Authentication Settings.
All POP authentication settings are independent. Even
if you have OAuth2.0 authentication in other POP authentication settings,
OAuth 2.0 authentication must be obtained separately.
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.
Tap the [Delete] key on each SMTP or POP authentication setting
screen to display a confirmation message. Tap the [OK] key to delete
the token.
When the token is deleted, the "Token" display will change
to [Not Retrieved].
The token status can be checked under "Token"
in any setting.
