[Hybrid Exchange] Connect Create PowerShell Session to Exchange Online

Question

I'm working with Windows 10, and want to connect to Exchange Online, but facing some errors.

It's my code:

$adm_credential = Get-Credential

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office.de/powershell-liveid/ -Credential $adm_credential -Authentication Basic -AllowRedirection

And I got this error:

New-PSSession : [outlook.office.de] Connecting to remote server outlook.office.de failed with the following error
message :
[ClientAccessServer=FRXPR01CA0067,BackEndServer=,RequestId=c4cbbb6f-9bc6-4b14-8d86-e15333e12777,TimeStamp=5/21/2019

I checked all prerequisites, and didn't find any exception.

PowerShell sessions could be established to on-premise AD, on-premise Exchange, AzureAD, msolService, and so on.

I googled the error, and tried every solution I could get.

How can I establish the connection? Thank you in advance.

chenryleeIs MFA enabled in the tenant ? In case, you need to install and use appropriate Powershell modules

chenrylee&nbsp;&nbsp;It seems that you've got the wrong ConnectionUri&nbsp;https://outlook.office.de/powershell-liveid/- You should use this&nbsp;Set-ExecutionPolicy RemoteSigned$UserCredential = Get-Credential$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirectionImport-PSSession $Session -DisableNameChecking&nbsp;- Most expected reason, your tenant is not registered in Germany.&nbsp;Regards,AkshayExchange admin | Apps4Rent&nbsp;
