Microsoft announced that from September 1, 2025, the Viva Engage (formerly Yammer) connector no longer supports OAuth 2.0 connections.

New connections must use Entra ID authentication. Existing OAuth 2.0 connections will work until November 15, 2025, after which they must be switched to Entra ID authentication to avoid disruptions.
