Hi, We have some custom requirement where we are looking for Exchange 2007/2010 powershell command/admin console to manage the Exchange setup which is installed in different forest. Ex: I have a work station in Domain A and wanted manage the exchange setup which is in Domain B and all together its a different forest and exchange setup in different forest. Do we have some solution like AD Trust relationship etc ? to manage the remote forest Exchange setup ? Pls guide me and let me know if any more details required.Regards:Mahesh

Hi Mike, Thanks for your revert and will check this option really... Does this work for Exchange 2007 as well ? Regards:Mahesh

Hi, I was trying to conect Exchange 2010 server using the commands shared by Mike but i am getting below error and not able to fix. I tried by different authentication method as Basic,Kerberos but still no luck. I tried from two work stations, one is in work group and other one is in different forest/Domain than the Exchange setup. Pls help... PS C:\Users\Administrator> $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://EXCH2010SRV/PowerShell/ -Authentication Negotiate -Credential $Usercredential [exch2010srv] Connecting to remote server failed with the following error message : The WinRM client cannot process the request. The authentication mechanism requested by the client is not supported by the server or unencrypted traffic is disabled in the service configuration. Verify the unencrypted traffic setting in the service configuration or specify one of the authentication mechanisms supported by the server. To use Kerberos, specify the computer name as the remote destination. Also verify that the client computer and the destination computer are joined to a domain. To use Basic, s pecify the computer name as the remote destination, specify Basic authentication and provide user name and password.

Hi Mahesh, Can you try to run the command without the "-Authentication Negotiate " and test to see if you can initiate the session?

Hi, Tried without "-Authentication Negotiate " also but it couldnt succeed Regards:Mahesh

From the command prompt/PowerShell, please set the TrustedHosts from * to i.e. from wildchar * to nothing by running the command Winrm set winrm/config/client `@`{TrustedHosts=```} Then add "-Authentication Negotiate" and run the command. Please run the command with -verbose as well.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
