Hi
I have a new Exchange 2016 Environment and have enabled the Windows Firewall. Exchange does add the Firewall rules by self. I have test with a User UM (Voicemail) works.
If I start the UM Test-cmdlet there's end in a timeout if the Firewall is on. i can't se something in the logs. What can I do to resolve this issue?
Test-UMConnectivityReasonForFailure:Waitfor the diagnostic sequence response. timed out after 20 seconds.
