Question

HI!
When i run the following comand to connect o office 365 by powershell i get the error bellow.
It's been a while since i use ps to connect to o365 can anyone help me with what is missing?

Import-Module MSOnline
$TenantUname="user"
$TenantPass = ConvertTo-SecureString "pass" -AsPlainText -Force
$TenantCredentials = new-object -typename System.Management.Automation.PSCredential -argumentlist $TenantUname, $TenantPass
Connect-MsolService -Credential $TenantCredentials

Error:
Connect-MsolService: Could not load type 'System.Security.Cryptography.SHA256Cng' from assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Answer 1

Are you using PowerShell 7? That object type isn't supported by .Net Core.

Answer 2

Hello @Tiago Oliveira

I would recommend to check which version of Powershell you are using by running $PSVersionTable in Powershell.

If you are running version 7, you may need to install and update the AzureAD module to work succesfully. Run the next from elevated Powershell window:

Install-Module AzureAD
Import-Module AzureAD -UseWindowsPowerShell

Hope this helps with your query,

Hi!

i fixed the script by changing it to the following

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Import-Module MSOnline -UseWindowsPowerShell
$TenantUname="user"
$TenantPass = ConvertTo-SecureString "pass" -AsPlainText -Force
$TenantCredentials = new-object -typename System.Management.Automation.PSCredential -argumentlist $TenantUname, $TenantPass
Connect-MsolService -Credential $TenantCredentials
