For Skype for Business Online organizations, you can use the Remote PowerShell in Office 365 to enable your Skype for Business users to use the Skype for Business client or the Skype for Business (Lync) client user interface. The default setting is for users to user the Skype for Business client user interface. You can apply the client user interface policy settings to your entire organization, groups, multiple and single users.

Q2. Where can I download Skype for Business since it does not appear to be included with the Office365 download file? ====================== A2. You need to manually update your Office application, then you will be able to upgrade to Skype for Business. You can to do this on your Outlook client: Open your Outlook client -> FILE -> Office Account -> Apply updates

And this issue is more related to Office 365 application, we would like to give a hand, but we are not the specialists in this filed. Thanks for your understanding.

Best regards,

Eric
