How to Sign out from Microsoft Teams from Skype for business

Trying to login my Office 365 Skype for business from the corporate  Skype for Business Client , once login to Office 365 the client show the landing page to force me log on with the Teams by using browser.

 Try to figure out how to enable  Office 365 Skype for business instead install the the Teams Apps , anyway still figuring out about this.

Anyway now the problem i have faced is i am unable to logout from the Skype for Business Client from the Teams , try to log out from the Skype for Business Client and log in again ..but during login no chance for me to key in my corporate domain account direct showed the Teams Page information.

Try to sing out from notebook even restart the notebook but is not help at all , so the finally trick for me to log in back to my corporate domain account to skype on premise is .....

Turn off the network then the Skype client log in page will stop there for you to change the login name !!! 

Hope this help those stuck on it !! ha ha
