Cause: Autodiscovery Uri was not correctly configured or unreachable, that there is a problem with the Proxy, or other errors.
Resolution:
Check event details.  Check autodiscovery Uri is properly configured and reachable. Check that proxy setting is properly configured and reachable.  Validate Skype for Business to Exchange Autodiscovery configuration by following the trouble shooting guide. If problem persists, notify your organization's support team with the event details.
