Every since Microsoft bought off Skype, they have decided that they are NOT going to let you go offline. Thats how much they love you being online. So well, you have to knock off Microsoft from your Skype account to be able to go offline.

- Unlink the Microsoft Account. Once unlinked, your Account settings page will look like the screenshot below.
- In a few seconds, knocking Microsoft out of your Skype account should bear results.
- Follow suit for other (IT) problems in your life. Say no to Microsoft.
