Unable to sign into Onenote on any device.
Phone: Error 0xE0000641
Web app: Reference number: ebf110be-9a30-484f-b7a5-9d6fc9fe5377
Spoke to Microsoft support who confirmed it is an issue with my Onenote account not my devices. No issues logging on to any other product; Hotmail, Excel, Word are all letting me log on and use the service.
