1709 Bugs with Outlook 2013 and Skype 2016

I recently ran into a situation where I ended up with a desktop edition of Skype for Business which is an option for Microsoft 365 Business editions.  If you want to remove Skype / Skype for Business off your machine you will need to uninstall your Microsoft 365 app (desktop edition) which is actually Office 16 and then install the Microsoft 365 CoPilot desktop app.  

Using PowerShell (Run as Administrator) does not uninstall Skype for Business in Office 16:

Get-ChildItem -Path "C:\Program Files (x86)\Microsoft Office\root\Office16\*lync*" -Recurse | Remove-Item
Get-AppxPackage *Microsoft.SkypeApp* | Remove-AppxPackage
-or-
Get-WmiObject -Class Win32_Product | Where { $_.Name -eq "Microsoft Lync 2013" } | ForEach { $_.Uninstall() }

Clicking the Uninstall option on the Windows Start menu for the Skype for Business application will not uninstall Skype for Business in Office 16.
