ITGuyNW Posted January 28, 2021 Posted January 28, 2021 Hi all, We are seeing an issue in School where some cannot reach login.microsoftonline.com . It seems Teams uses this to grab the login page. Now this is happening to random users, both app and the web version. I thought it might have been a Chrome update but its even doing it in IE11. The only other thing we have done/are doing is rolling out the latest Teams and using the machine-wide installer. Could that update be messing up accessing the login page? Even if you try and reach login.microsoftonline.com in IE11? We are on Roaming profiles here (again, could that be messing with things?) We rang BT Lancashire who shrugged. So has anyone else had any weird goings on with accessing login.microsoftonline.com and logging into Teams?
