Hi anonymous user,
SQL server DB Mail using below authentications.
Windows Authentication using Database Engine service credentials
Connection is made to the SMTP server using the credentials configured for the SQL Server Database Engine service.
Basic Authentication
Specify the user name and password required by the SMTP server.
Anonymous authentication
Mail is sent to the SMTP server without login credentials. Use this option when the SMTP server does not require authentication.
If the basic authentication is end of supported in Exchange, then we can also use the other two authentications to configure SQL DB mail.
Refer to MS document Configure Database Mail.
