If you select your Azure AD > Applications > Add >Īdd an application from Gallery > search for 'Skype' you will find the application which you can add to your Azure AD. Skype - Consumer is an application that we have available with-in the SaaS Application Gallery which you will find with-in the classic management portal under the Azure Active Directory Extension. There is more information on the Microsoft Tech Community here.First, let me apologise first of all as the above responses are not actually accurate responses in regard to your actual question here so let me clear things up for you. If you have your systems maintained by the MTR Premium service (previously as Microsoft Managed Meeting Rooms or MMR) then that will will remove the KB for you.

You can do this via the Windows Control Panel. To get your system working with Skype for Business again, you need to uninstall the KB. If you are on Windows 1903/1909, then KB4565351 would be offending KB that is causing the issue. If you were on Windows build 1803, then it was KB4571709 that would have blocked the sign in. So what has caused this? Well there are two Windows Updates, depending on your Windows version. Microsoft Teams still works, but Skype is affected. With a recent Windows Update, it has been discovered that it has affected the Skype for Business sign in on the device. If all goes well, we hope to push this new app version to 100% deployment in the Windows store by EOD tomorrow, 8/14.

We are currently testing a new version, 4.5.37, of the MTR app which implements a workaround. We have now identified the root cause of the issue as a change made in Windows which impacted some legacy SfB authentication code. Version 4.5.37.0 is now rolling out via the Microsoft Store.
