I use a mixture of Mac and Linux for most of my needs. I’ve run Windows virtual machines of same flavour or another but since .NET core 3 landed I’ve barely had to do even fire it up. There’s nowadays very little you can’t do in a non-Windows environment.
That doesn’t really extend (yet?) to remote administration of your Office365 tenant using Powershell.
I’m trying to configure some DNS bits for one of our domains that needs the Exchange Online V2 Powershell module. Come with me as I disappear down a rabbit hole of getting this working.
(I know Powershell for macOS is a thing; but I’ve not yet experimented with it. Maybe I will if I can (or can’t!) get this working.
I fired up a dust ol’ Win10 virtual machine and started following the guide. Windows Powershell was in the start menu so gave it a go. No idea what version so
gave me 5.1.16299.98. That ought to do nicely? Onwards!
This is required to allow an exception in the Windows firewall. But doing it the first time failed. Yep, you need to run Powershell as Administrator. Wakey wakey.
OK, so running as Admin and:
WinRM is not set up to receive requests on this machine. The following changes must be made: Start the WinRM service. Set the WinRM service type to delayed auto start. Make these changes [y/n]?
Hit ‘y’ and… a wall of error:
Message = WinRM firewall exception will not work since one of the network connection types on this machine is set to Public. Change the network connection type to either Domain or Private and try again.
OK, so in my case I’m in a virtual machine so I have a couple of network adaptors, including one virtual which was set to public but otherwise doing nothing. Disabling that allow the firewall exception to go in. Following the rest seemed to say this was working.
The rabbit hole opens
Onwards to ‘installing the Exo V2 module’. Step 1: you need PowershellGet. Innocuous looking sub-link. OK.
Before updating PowerShellGet, you should always install the latest NuGet provider.
Install-PackageProvider -Name NuGet -Force
WARNING: MSG:UnableToDownload «https://go.microsoft.com/fwlink/?LinkID=627338&clcid=0x409» «» WARNING: Unable to download the list of available providers. Check your internet connection.

Please check if the specified package has the tags. At line:1 char:1 + Install-PackageProvider -Name NuGet -Force
Now, there are actually a couple of things going on here; one a lack of repositories to get stuff from AND ALSO a TLS error. I ‘fixed’ the TLS error first:
and you should now be able to install NuGet:
Install-PackageProvider -Name NuGet -Force Name Version Source Summary ---- ------- ------ ------- nuget 126.96.36.199 https://onege... NuGet provider for the OneGet meta-package manager
If you now try and install PowerShellGet:
Install-Module -Name PowerShellGet -Force
It might work… but also it might not:
PackageManagement\Install-Package : No match was found for the specified search criteria and module name 'PowerShellGet'. Try Get-PSRepository to see all available registered module repositories.
If you follow its advice and do a
this is a bit of a clue:
PS C:\WINDOWS\system32> Get-PSRepository WARNING: Unable to find module repositories.
SO let’s give it some:
and once again:
PS C:\WINDOWS\system32> Install-Module -Name PowerShellGet -Force PS C:\WINDOWS\system32>
And we’ve now actually got PowerShellGet. Hurrah.
PS C:\WINDOWS\system32> Set-ExecutionPolicy RemoteSigned Execution Policy Change The execution policy helps protect you from scripts that you do not trust.

This all seemed to go OK.
