Microsoft Exchange Online - Reconfigure Existing SMTP Mail Servers Configured with Basic Authentication to use OAuth2

If Oracle Analytics currently uses Microsoft Exchange Online to send emails with Basic authentication, you must update your mail server configuration to use OAuth2 authentication before September 2025.

Microsoft Exchange Online is a cloud-based email and calendaring service, and it's part of Microsoft 365. Microsoft is deprecating Basic authentication for Microsoft 365 (including SMTP), in favor of modern authentication (OAuth2) and will fully remove support for Basic authentication by September 2025. See Deprecation of Basic Authentication in Microsoft Exchange Online.

To continue sending emails through Exchange Online, you must reconfigure your mail server to use OAuth2 authentication and then update your mail settings in Oracle Analytics. Oracle recommends you transition to OAuth2 as soon as possible to ensure email features keep working in Oracle Analytics after September 2025.

Note:

The Microsoft Exchange Online platform supports several OAuth2 authentication flows. Currently, Oracle Analytics supports only the Client Credentials Flow.

1. In Microsoft Exchange, set up the Client Credentials OAuth2 flow for Oracle Analytics.
2. After registering Oracle Analytics as a client application, make a note of the client ID, client secret, and directory (tenant) ID. Oracle Analytics requires this information to connect to Microsoft Exchange.
3. In Oracle Analytics, navigate to the Console and click Mail Settings.
4. Go to Authentication, and change Basic to OAuth2.
5. For Provider, select Microsoft. For Grant Type, select Client Credentials.
6. Specify values for the Client ID, Client Secret, and Directory (Tenant) ID.
7. Click Save.
