Allow the option to use OAuth to authenticate SMTP
Currently to use SMTP the account has to support basic authentication which is not secure and is being deprecated by Microsoft for Azure accounts. In the next few months, Microsoft will be enforcing MFA on Azure accounts in phases and the only way around that for things like SMTP is to use OAuth. Since the current version does not allow OAuth authentication for SMTP, this will cause notification services that use email to stop functioning.
Allowing the option to use OAuth to authenticate SMTP would resolve this issue and allow users with Microsoft Tenants to continue using notification services.
