Test-OutlookConnectivity fails: Failed to find the probe result for invoke now request

In my Exchange 2013 lab environment (Exchange 2013 CU7 Multi-Role) cmdlet Test-OutlookConnectivity fails:

Test-OutlookConnectivity –ProbeIdentity 'OutlookRpcSelfTestProbe'
WARNING: An unexpected error has occurred and a Watson dump is being generated: Failed to find the probe result for invoke now request id 743eb01ee4f2436fa909a8206c029773 and probe workdefinition id 317.

Time zone setting on server: (UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna

After changing server time zone (& server reboot) to: (UTC -08:00) Pacific Time (US & Canada) cmdlet Test-OutlookConnectivity –ProbeIdentity 'OutlookRpcSelfTestProbe' runs successful:

The same warning may appear when running Invoke-Monitoring cmdlet and is also related to this time zone issue. For example: Invoke-MonitoringProbe -Identity OWA\OwaCtpProbe –Server server-name

This issue has been reported to MS. Don’t know when it will be fixed.
