Laravel, access smtp via modern authentication

Question

Hello,I have an application that sends mail with a customer's microsoft365 account.
Up to now SMTP authentication has been used, now customer wants to switch to modern Authentication.
A new application on azure has been created, and I have been provided with Tenant ID,
Application ID and Secret.

From what I understand in order to keep logged in I need a refresh token, I have followed diffrent guides but I'm not able to generate it.

is it possible to generate a token for a SMTP resource?

Hi @FFor

You can try using auth code flow to get an access token and a refresh token.

1.Run the URL in the browser to get the authorization code.

https://login.microsoftonline.com/{tenant id}/oauth2/v2.0/authorize?  
client_id={client id}  
&response_type=code  
&redirect_uri={redirect url}  
&response_mode=query  
&scope=https://graph.microsoft.com/SMTP.Send offline_access  
&state=12345  

2.Use the authorization code to redeem an access token and a refresh token.
