Install Skype for Business Online, Windows PowerShell Module:

After installing this I had trouble including the modules via : Import-Module SkypeOnlineConnector with the error

Import-Module : The specified module ‘SkypeOnlineConnector’ was not loaded because no valid

Skype for Business management shell installs in this location : C:\Program Files\Common Files\Skype for Business Online\Modules\

I used the below in Powershell to insert the .psd1 manually into my powershell


Import-Module -Name “C:\Program Files\Common Files\Skype for Business Online\Modules\SkypeOnlineConnector” -Verbose

Import-Module -Name “C:\Program Files\Common Files\Skype for Business Online\Modules\LyncOnlineConnector” -Verbose

This will still give the error Get-CsOAuthConfiguration : The term ‘Get-CsOAuthConfiguration’ is not recognized as the name of a cmdlet

Sign into 365 with your creds

$cred = Get-Credential

$session = New-CsOnlineSession -Credential $cred -Verbose

Import-PSSession -Session $session

I was then able to run

Set-CsOAuthConfiguration -ClientAdalAuthOverride Allowed
