I am trying to debug some connectivity issues related to accessing some on-prem mailboxes as well as some mailboxes that are being moved to Office 365.

I wanted to use the Remote Connectivity Analyzer but over the last couple of days I have been unable to get past the verification step so that I can actually run the tests. I have tried using Edge, IE11 and Chrome on Windows 10, and Windows Server 2012R2. I have had people looking over my shoulder as I type in the verification code to be sure I am putting in the correct code and I keep getting the following message:

"testconnectivity.microsoft.com says: Verifying the challenge failed. Please refresh the page and try again"

The page specifically says that the code is NOT case-sensitive but I have tried it both ways and still get the error.

Anyone run into this? Work arounds? Any thought would be a help,

Thanks in advance,

Mike Askwith
