Microsoft has announced that Exchange Online will permanently disable Basic Authentication for Client Submission (SMTP AUTH) in September 2025. After this date, applications and devices must use OAuth 2.0 for authentication when sending emails via SMTP AUTH

If you're using Exchange Online, here's what you need to know and how to prepare,

• If you are using Basic auth with Client Submission (SMTP AUTH) to send emails to recipients internal to your tenant, you can use High Volume Email for Microsoft 365.

• If you are using Basic auth with Client Submission (SMTP AUTH) to send emails to recipients internal and external to your tenant, you can use Azure Communication Services Email.

• If you have an Exchange Server on-premises in a hybrid configuration, you can continue to use Basic auth to authenticate with the Exchange Server on-premises.
