Hi there,

I am unable to login to my outlook mail account via Mac, iPad, iPhone (outlook app), and also LG products, in both private and non-private browsers. Below is the contents of the message that pops up. I've cleaned up all caches and history as well. What could be the issue here?

Back Filled Errors: Unhandled Rejection: SyntaxError: The string did not match the expected pattern. :undefined undefined:undefined undefine

err: Error: 500 esrc: StartupData et: ServerError
