无法使用PowerShell连接到Office 365

我想我错过了一个简单而重要的琐事.

一些信息：

>许可证是Office 365 Buisness Essential
> Azure AD正在运行
>我可以将powershell远程处理(WinRM)与其他服务器一起使用
>我使用管理员帐户
>我使用我的域并尝试了onmicrosoft.com域
>配置双因素身份验证(附加安全验证)

我尝试了以下内容

PS C:&;Import-Module MSOnline
PS C:&;$msolcred = get-credential
PS C:&;connect-msolservice -credential $msolcred
connect-msolservice : The user name or password is incorrect. Verify your user name,and then type your password again.

和

PS C:&; $O365Session = New-PSSession -ConfigurationName Microsoft.Exchange 
    -ConnectionUri https://ps.outlook.com/powershell 
    -Credential $msolcred -Authentication Basic 
    -AllowRedirection
New-PSSession : [ps.outlook.com] Connecting to remote server ps.outlook.com failed with the following error message : Access is denied. For more information,see the about_Remote_Troubleshooting Help topic.

我使用了不同的连接uri

PS C:&; $Session = New-PSSession -ConfigurationName Microsoft.Exchange 
    -ConnectionUri https://outlook.office365.com/powershell-liveid/ 
    -Credential $msolcred2 -Authentication Basic 
    -AllowRedirection
New-PSSession : [outlook.office365.com] Connecting to remote server outlook.office365.com failed with the following error message :
