The Skype for Business network assessment tool has been updated (version 2017.1.0.51) and is now taking into account Microsoft Teams in addition of Skype for Business.

You can download the updated network assessment from https://www.microsoft.com/en-us/download/details.aspx?id=53885

Once installed, there is no shortcuts whatsoever; you need to browse to C:\Program Files\Microsoft Skype for Business Network Assessment Tool and run the NetworkAssessmentTool.exe file to start. As this is still a command line executable, it is recommended to run it from a command prompt

Do not forget to run the tool from the install location; if you run it like that “C:\Program Files\Microsoft Skype for Business Network Assessment\NetworkAssessmentTool.exe” the assessment will fail because the tool is not able to locate the tone.wma file; or edit the NetworkAssessmentTool.exe.config file to define the full path to the file (update the WMAFilePath key)

NOTE you can also edit the location where the result reports will be saved by editing the ResultFilePath and/or the OutputFilePath keys

When you launch the tool, you may be prompted to authorize the tool to go through the Windows Firewall

Interestingly, the tool continues to run in the background even if you do not answer yet to this request

Once completed, the result is available in the AppData\Local\Microsoft Skype for Business Assessment Tool folder of your user profile

Additional parameters can be used when running the tool, depending of what you want to assess

  • networkassessementtool.exe with no parameter runs the performance tests
  • networkassessmenttool.exe /connectivitycheck checks the connectivity with Office 365 services (SfB / Teams)
  • networkassessmenttool.exe /connectivitycheck /verbose checks the connectivity in verbose mode

You can analyze the results using the ResultAnalyzer.exe file by providing the path the test result file (the TSV file generated when using the assessment tool with no parameters)
