Steps to reproduce

after importing AzureAd module and Calling the Connect-AzureAd Cmdlet
an interactive form opens to supply credentials and provide MFA authentication 

Install-Module -Name "AzureAD" -Verbose -Force -AllowClobber
Import-Module -Name "AzureAD" -Verbose -Force
Get-Module -Name "AzureAD"-ListAvailable | Select-object Name, Version
Connect-AzureAD

Expected behavior

The Connect-AzureAd Cmdlet should continue successfully and establish a connection with Azure AD

Actual behavior

connect-azuread : One or more errors occurred.

@aollivierre Please move the issue to Azure feedback site.
Perhaps it is here https://feedback.azure.com/forums/169401-azure-active-directory

I don't get why this is moved to the azure feedback site. I am encountering this exact same error on the 7-Preview. Here is my version info:

Works fine with Desktop 5.1 on my current windows 10 build.

@toddwseattle We need a simply repo to discover a root of the issue. Azure site is good place to start.

I'm logging in with my Office365 admin / AzureAD address that has 2 factor auth. The popup comes up; i enter the password and text code; and then I get the errors.
What else do you need?

[SteveL-MSFT]

@toddwseattle please see #11070

[O365scripts]

I was having issues connecting to the SFB module as well when using the v7 but was unable to connect properly. After switching my VS Code's shell to the regular 5.1 I was able to login properly to that service.

[swinster]

Exactly the same behaviours as @O365scripts

[swinster]

Noted this to when attempting to connect to O365. Posted a question to https://docs.microsoft.com/en-us/office365/enterprise/powershell/connect-to-office-365-powershell#connect-with-the-microsoft-azure-active-directory-module-for-windows-powershell, and the related GitHub, but as noted in that issue, is looks like PS Core is not support for AzureAD or the Msol named CmdLets.

I guess there is not much that can by done until Azure Az catches up.

Got error when run command:

Connect-AzureAD
Connect-AzureAD: One or more errors occurred.

Sorry, Screen shot is not allowed to attach. Add attachment here should be a cool feature.
The PowerShell is version 7.

[jianwshen]

This happens when I use command
$Credential = Get-Credential
Connect-AzureAD -Credential $Credential

I'm getting this error too - fresh install of PowerShell on osx.
