Resolution

To fix this issue, install the March 5, 2019, update (KB4462190) for Skype for Business 2016.
Note After applying this update, you can use one of the following options to disable the banner that is shown when the Persistent Chat server is down. 

  • You can create a Group Policy Object (GPO) to add a new DWORD registry key EnablePersistentChatPoolDown and set the value to 0 in any one of these registry paths:
    HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Office\16.0\Lync
    or
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Office\16.0\Lync
  • Alternatively, you can create a custom policy entry and add it to the client policy:
    $x = New-CsClientPolicyEntry -Name "EnablePersistentChatPoolDown" -Value "false"
    Set-CsClientPolicy -Identity "<ClientPolicyName>" -PolicyEntry @{Add=$x}
