PowerShell is unable to connect to Skype for Business Online in a hybrid environment. To Connect to Skype for Business PowerShell commonly use:
Import-Module SkypeOnlineConnector
$Cred = Get-Credential
$Session = New-CSOnlineSession -credential $CredOr (with all tools installed):
#cred = Get-Credential
$session = New-CsOnlineSession -Credential $cred
Import-PSSession $sessionBut, Administrators who have a Skype for Business hybrid deployment may receive the following error message when they try to connect to Skype for Business Online Remote PowerShell:
Get-CsPowerShellEndpoint : The remote server returned an error: (503) Server Unavailable.
At C:\Program Files\Common Files\Skype for Business
Online\Modules\SkypeOnlineConnector\SkypeOnlineConnectorStartup.psm1:94 char:26
+ … $targetUri = Get-CsPowerShellEndpoint -TargetDomain $adminDomain
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Get-CsPowerShellEndpoint], WebException
+ FullyQualifiedErrorId : System.Net.WebException,Microsoft.Rtc.Management.OnlineConnector.GetPowerShellEndpointCmDletThis is expected behavior for a Hybrid environment and the issue occurs when the DNS records for LyncDiscover are pointed to the on-premises Skype for Business environment.
To resolve this issue, run the cmdlet again, but instead, add the -OverrideAdminDomain parameter. Use the default domain that was included with your Office 365 subscription; for example, use name.onmicrosoft.com:
Import-Module SkypeOnlineConnector
$Cred = Get-Credential
$Session = New-CSOnlineSession -credential $Cred -OverrideAdminDomain “name.onmicrosoft.com”These easy steps have now provided remote PowerShell access to the connected Skype for Business Online. To test connectivity simply try running Get-CsUser.
You my friend are a legend! Just the command I needed!!
