I have a Sharepoint web application running on SAML security (based on user e-mail). I have a problem with one user that is not managing to log-in. Basically the IT admin, have done a mistake and have entered a typo in the user's email address (even if you look for the email in outlook, it was not showing correctly). They have now fixed this. Now, if you search for the contact in outlook it is correct.
However, if the user tries to log-in in Sharepoint, it is showing an anauthorized message. This message also shows a "you are logg-in as email" message. However, the email here is still with the typo.
I have already been going back and forth with the admin team to check it from their end but they are saying it is ok. I would like to know how best to investigate this issue and what can I do to get more information.
