Outlook app sign in problems
Hello, I am getting an authentification error trying to sign in the outlook mobile app.
I also cannot sign in to outlook.com as it tells me "You need to create an Outlook.com email address to continue. We'll add it to your account as an alias."
I can sign in to the desktop app on pc without any problem.
Does anyone have any ideas?
Many thanks
