How authenticate an SMTP connection using oauth2 for sending mail ( office 365) in c#?
Hello everyone,
I have a little question about SMTP:
How authenticate an SMTP connection using oauth2 for sending mail ( office 365) in c#?
The application is registered on Azure Ad (Microsoft entry ID). On this one I have active Microsoft graph and Microsoft exchange online
If it is not possible there is a work around
Thanks in advance.

Are you trying to use the MS graph APIs? I think all you need is to use https://learn.microsoft.com/en-us/graph/api/user-sendmail?view=graph-rest-1.0&tabs=http and have a bearer token (which oauth2 would give you I think)
user: sendMail - Microsoft Graph v1.0
Send the message specified in the request body using either JSON or MIME format.
I think SMTP is being deprecated
I want to use mailkit.
