I am trying to renew our S4B Oauth Certificate, but it fails both in the GUI and in PowerShell.
The certificate issues without problem but when it tries to assign (set-cscertificate) it throws this error:
Command execution failed: Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).
Via Powershell:
Set-CsCertificate : Command execution failed: Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx). At line:1 char:1 + Set-CsCertificate -Identity Global -Type OAuth -Thumbprint 77eb8f26eecc8c3149d04 ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~ + CategoryInfo : InvalidOperation: (:) [Set-CsCertificate], FormatException + FullyQualifiedErrorId : ProcessingFailed,Microsoft.Rtc.Management.Deploy ment.SetCertificateCmdlet
Via GUI:

Any ideas how to get it assigned?
Thanks!
