He decided it was a network problem and rang off, saying that he was not trained to do networks. I could not fix the problem, so I rang Microsoft help line and had a long conversation with an engineer.
Each time I logged on with my laptop I got a message like 'fix your Microsoft account or apps will not work on your other devices'. As a result, I ended up with different usernames and passwords on the three machines, some with correct details, and some with different ones. Last Monday while logging in to Skype with my usual frequently used and long held username and password, Skype refused to continue until I had entered my Microsoft account username and password. I also have a common account for Skype that worked on them all until Microsoft bought out Skype.
