As of NetSuite 2024.1, the Outbound Single Sign-on (SuiteSignOn) feature will no longer be supported in
non-production accounts, such as sandbox accounts. As of NetSuite 2024.2, this feature will no longer be
supported in production accounts.
Multiple test windows will be scheduled, and more proactive feature change notifications will be sent to
prepare you for this change before the release of NetSuite 2024.2.
As an alternative to SuiteSignOn, you can use the NetSuite as OIDC Provider feature. For more
information, see the help topic NetSuite as OIDC Provider.
