Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi bogdan.albei.gmail.com,
With a "third party IDP", I suppose you're using a third party SSO solution rather than the Microsoft official ADFS/SSO deployment. If that's true, I'm afraid we cannot provide corresponding technical support in our forum, which is dedicated to Office 365 online service.
However, if I misunderstood and you are actually using ADFS/SSO deployment, please post back. Further assistance will be provided here. We highly appreciate your understanding.
Thanks,
Brook
