I have about 100 contacts linked to my Microsoft account (as shown on people.live.com) who aren't mine and I can't figure out a way to delete them. My whole Windows 10 calendar is filled with random birthdays of people I have no clue who they are. It looks like they are Skype contacts, but when I try to recover the Skype account linked with my Microsoft account, Skype denies it and tells me they can't verify it's me. I've tried contacting both Microsoft & Skype via phone and no one understands the issue. I've been told my Microsoft account isn't linked with any Skype account, but it clearly is, as you can see in this cropped screenshot (I DON'T KNOW ANY OF THESE PEOPLE):
I don't know ANY of these people. I've been told I have to "recover" my Skype, but I've tried MULTIPLE times and Skype always denies that I own the account. I'm guessing the Skype account was hacked. I don't even care about recovering my old Skype account, but I don't want random people's birthdays on my Windows 10 Calendar, for example!
