I created the MS account through the web interface, and didn't link it with the pc. I've just checked and the pc is still using it's local account with no sign of the MS account from the web (which is as it should be). Thanks for your suggestion. Based on that I've checked the profile for the address book on skype and apparently the test account email is not shown. I did talk with Skype support, and they wouldn't do anything. They've clearly been trained what to say about this issue, and to not even begin to attempt to do anything to resolve it. I'm think I will create my own luck here, and migrate away from Skype fully, and MS as much as I can, because of these abusive Dark Patterns, the tricking users into things they don't want while hoovering up personal information are too prevalent in MS now. For any readers who aren't familiar with the issues, there are a number of writeups and arstechnica is a good source - the big and clear events are the win 10 upgrade dialog, the tricks to make the local PC account harder to use when installing Windows, and this latest example of linking separate accounts without asking while breaking the usual boundaries of web pages isolation from other things on your PC and not allowing unlinking of the accounts forcibly and unexpectedly linked. It's part of a pattern of abusive behaviour from Dark Patterns of UX, and I expect them to continue exploiting their customers in these ways. So I'm going to create my own luck by removing as much of their influence from my life as possible. Starting with skype :) (Edited for a grammar fix.)
