When I was trying to install the Skype for business online I was getting different errors, the first was
“must have C++ Redistributable (x64) – 14.10.25008 installed as a Minimum Runtime.”
while I was trying to install the module.
To connect to Skype online, type the follow lines
$userCredential = Get-Credential
$sfbSession = New-CsOnlineSession -Credential $userCredential
to make sure that you have the module ready, you can type Get-CsOnlineUser Username, for example:
and you will see the properties for that user.
