K-State webmail is currently encountering sign-in errors due to updates to sign-in systems. This problem occurs primarily on Google Chrome and affects all operating systems. ITS staff are aware of the issue and are applying changes as necessary to resolve the problem.
Users who encounter sign-in errors will continue to experience issues until they clear their cache and attempt to sign in again. Instructions on how to do so can be found here: https://kstate.service-now.com/kb_view.do?sysparm_article=KB12251.
