Connect to Exchange Online PowerShell using MFA

Hi,

 

I'm trying to follow the instructions on this page: https://technet.microsoft.com/en-us/library/mt775114(v=exchg.160).aspx

 

which all seem pretty easy to follow. I'm on a brand new install of Windows 10 Pro, and when I try to run the file I download from Exchange Admin I get the error in the image attached.

 

I've tried this on a few Win 10 Pro PC's, some brand new some a few months old, I get the same issue.

 

What's the correct way to overcome this so I can install?

 

This is the error that's in the log file:

 

ERROR SUMMARY
Below is a summary of the errors, details of these errors are listed later in the log.
* Activation of E:\Microsoft.Online.CSE.PSModule.Client.application resulted in exception. Following failure messages were detected:
+ Deployment and application do not have matching security zones.

  • That's the joy of running those click-once apps...

     

    Try re-donwloading/installing it via IE, see if it makes a difference. If it still doesnt work, you probably have some restrictions set on the IE zones that prevents the app from running. Running .Net code needs to be enabled for example.
