Hey&nbsp;scl-family_1,&nbsp;It looks to me like the email address is not getting mapped properly to the username or "nameID" inside of your SAML application. Essentially something else is being tested against Office 365 from the IDP.&nbsp;To fix this, I would look at creating a claims rule inside of ADFS to change the nameID to the email address for your users.&nbsp;This article walks through the process of creating that claim.https://help.screensteps.com/m/remote_authentication/l/841006-troubleshooting-saml-for-adfs&nbsp;Once that is in place, I would expect you to resolve the error you are seeing.&nbsp;Adam

Dear Adam,I have tried your suggestion but same result and error.I am using Gluu Idp.Please find doc for Integration Office365 in Gluu.https://gluu.org/docs/ce/3.1.3/integration/saas/office/IDP requires three attributes IDPEmail, ImmutableID and objectguidyou can find in doc that IDP requires nameID 'ImmutableID' .This is a 'persistent' type nameID; base attribute 'objectguid'
