Azure Portal: SSO initiated login with external provider

I successfully configured Azure to work with an external IdP according to https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-fed-saml-idp
However if I try to do an IdP initiated login, it seems that the SSO service https://login.microsoftonline.com does not parse the RelayState
accordingly to http://docs.oasis-open.org/security/saml/Post2.0/sstc-saml-tech-overview-2.0-cd-02.html#5.1.4.IdP-Initiated%20SSO:%20%20POST%20Binding|outline



If I use the IdP initiated login URL:



https://my-sso-idp.cloud/saml2/idp/SSOService.php?spentityid=urn:federation:MicrosoftOnline&RelayState=https://portal.azure.com



the login works fine, but then I get redirect to https://www.office.com/?auth=2&home=1



If I finally type https://portal.azure.com in the same browser tab, I can access the Azure portal due to already successfully logged in via SSO.



Does anybody know why the Micrsoft SSO ignores the RelayState argument?



Cheers Jonas
