Skype for Business Outdated Client Issue : TurnAuthUnknownUser

Hi Aaron,

Thanks for this. I just wanted to clarify a couple of points: firstly, your post above says that the attached CQD report to "... identifiy the number of incidences of this error [TurnAuthUnknownUser] within your environment". I don't believe that it does. The report description in the CQDX file says that it ''... summarizes the client versions in use for which it is recommended that the latest update be installed." It does not look at fail-to-establish occurrences at all. Secondly, I take the description in the report itself to mean that it will return a list of all OC versions in use that are specifically susceptible to this issue at hand. But looking at the CQD report (dimensions, measurements, filters) it just returns a list of all OC versions (to be precise - those that have made at least one call over the measured period). So in essence, the script is just returning a list of OC clients in use within the tenant and the guidance behind this is 'stayed patched folks'. If that's the case, I think it's worth clarifying that in your post above as the report does not seem to report on this specific issue.

Thanks,

Garry
