Unable to connect to Skype Online for Business - "winrm" issues
Solution 1
First of all, this is the method that gets me connected without any additional settings, except having S4B Online Windows PowerShell Module v6.0.9276 installed.
This is the quote from a short guide on Technet
$sfboSession = New-CsOnlineSession -Credential $credential
Import-PSSession $sfboSession
this gets me connected without error:
By the looks of it, it might be network packet inspection or SSL proxy breaking SSL (as it did on Cisco ASAs with SMTP inspection turned on, ruining Exchange TLS connections).
New-CsOnlineSession
can be be run with -SessionOption
parameter to supply proxy settings information. Configure session with proxy settings inherited from system configuration:
$proxysettings = New-PSSessionOption -ProxyAccessType WinHttpConfig
New-CsOnlineSession -Credential $credential -SessionOption $proxysettings
Import-PSSession $sfboSession
There are more proxy options, including authentication mechanisms and credentials, for New-PSSessionOption
cmdlet.
Solution 2
Our Exchange admin tried on a VM and got the same error. But it works fine on his workstation when he’s remotely connected to our network using Direct Access. That pointed to the network issue.
He found out that the firewall was blocking it and we got it to work with this:
$proxysettings = New-PSSessionOption -ProxyAccessType AutoDetect
New-CsOnlineSession -SessionOption $proxysettings

I am attempting to manage Skype Online for Business via the
LyncOnlineConnector
PowerShell module. I have had no trouble whatsoever connecting to remote exchange. However, I am now trying to do the exact same thing usingNew-CsOnlineSession
rather thanNew-PSSession
(used to connect to o365).Importing the lync connector works fine. However, when I try to build the session (verbose):
VERBOSE: Determining domain to admin VERBOSE: AdminDomain = 'x.com' VERBOSE: Discovering PowerShell endpoint URI VERBOSE: TargetUri = 'https://admin1a.online.lync.com/OcsPowershellOAuth' VERBOSE: GET https://admin1a.online.lync.com/OcsPowershellOAuth with 0-byte payload VERBOSE: AuthUri = 'https://login.windows.net/common/oauth2/authorize' VERBOSE: Requesting authentication token VERBOSE: Success VERBOSE: Initializing remote session New-PSSession : [admin1a.online.lync.com] Connecting to remote server admin1a.online.lync.com failed with the following error message : The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". For more information, see the about_Remote_Troubleshooting Help topic. At C:\Program Files\Common Files\Skype for Business Online\Modules\SkypeOnlineConnector\SkypeOnlineConnectorStartup.psm1:147 char:16 + $session = New-PSSession -ConnectionUri $ConnectionUri.Uri -Credential $cred ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [New-PSSession], PSRemotin gTransportException + FullyQualifiedErrorId : CannotConnect,PSSessionOpenFailed
What perplexes me is that I had this same issue with exchange initially, however setting the execution policy (remote force) and running
winrm quickconfig
seemed to fix everything.I've tried every suggestion related to winrm I can find, but nothing seems to change this error. I've opened ports, run the command as different users / admin, recreated the session often, ran the commands here, as well as numerous other things from the 'net that I can't remember anymore. Nothing changes my results at all.

MacroPower almost 7 yearsSo I think you almost got it. I took a look at the
-SessionOption
param to see if I could try using non-SSL for testing. I ended up finding another script github.com/pecigonzalo/Oh-My-Posh/blob/master/plugins/o365/… That used that param to define proxy settings. That fixed my problem 100%. If you edit your answer to include this I will accept it. :) Thank you! -
Grigory Sergeev almost 7 years@MacroPower glad to be of help. By the way, what kind of proxy do you have and which parameter have you used with proxyoption? I have tried IEConfig out of curiosity and that broke my connection, trying to look for script URL that doesn't exist (we used to have a proxy script back in a daym, but currently IE displays autodetect, not autoconfigure from url)
