Public Skype federation problems RRS feed

  • Question

  • My Skype For Business 2015 installation is federated with public Skype since two years. Some users started to report delay and unable to send invites to pulbic skype accounts. This delay usually lasts two days and sometimes the communication with public accounts stop.
    I checked SfB Edge status and all the services are running, ports are listenning and digital certificate isn't expired. Follow the SfB configuration:

    PS C:\Users\administrator> Get-CsPublicProvider
    Identity                         : Skype
    Name                             : Skype
    ProxyFqdn                        : federation.messenger.msn.com
    IconUrl                          : https://images.edge.messenger.live.com/Messe
                                       nger_16x16.png
    NameDecorationDomain             : msn.com
    NameDecorationRoutingDomain      : msn.com
    NameDecorationExcludedDomainList : msn.com,outlook.com,live.com,hotmail.com
    VerificationLevel                : AlwaysVerifiable
    Enabled                          : True
    EnableSkypeIdRouting             : True
    EnableSkypeDirectorySearch       : True

    Versão do SfB 2015 Edge: 6.0.9319.259
    Versão do SfB 2015 Front End: 6.0.9319.259

    Is anything else I can check?

  • Hi rlpCTINET,

    Which version of SFB client do the users use? Please try to use the SFB client latest version then check this issue again. Please go through the official document below and make sure all the settings work fine, and make sure your environment meets the requirements: Deploy Skype Connectivity in Skype for Business Server

    In addition, if all users have this issue in your environment, you could try to remove the PIC provider, then create a new PIC provider by running the following command:
    Remove-CsPublicProvider -Identity <identity-name>
    New-CsPublicProvider -Identity Skype -ProxyFqdn federation.messenger.msn.com -IconUrl https://images.edge.messenger.live.com/Messenger_16x16.png -NameDecorationRoutingDomain msn.com -NameDecorationExcludedDomainList "msn.com,outlook.com,live.com,hotmail.com" -Enabled $true -EnableSkypeIdRouting $true -EnableSkypeDirectorySearch $true

    Best Regards,
    Evan Jiang
