It sounds like there may be an issue with the permissions or configuration of your Skype for Business deployment. Here are a few troubleshooting steps you can try:
- Make sure that the CSadministrator account has the necessary permissions to access the Skype for Business control panel. You may need to check the permissions assigned to the account in Active Directory or Skype for Business Server Control Panel.
- Check the Skype for Business Server event logs for any errors or warnings that may indicate the cause of the issue.
- Verify that all the Skype for Business services are running and are configured correctly. You can check this in the Services console on the server.
- Check the IIS logs on the server to see if there are any errors or warnings related to the Skype for Business control panel.
