Exchange 2016 On-Prem - One DB of Users not able to conenct Outlook client

I've verified both of these, and they are setup like the other 3 exchange servers in our system. Any other suggestions on what may be the cause? Exchange Management Shell is not working either.  Gives the below error when launched:

New-PSSession : [DELETEDBYPOSTER] Connecting to remote server mchexchsvr04.chc.net failed with the following
error message : The WinRM client cannot process the request. The WinRM client tried to use Kerberos authentication
mechanism, but the destination computer (DELETEDBYPOSTER:80) returned an 'access denied' error. Change the
configuration to allow Kerberos authentication mechanism to be used or specify one of the authentication mechanisms
supported by the server. To use Kerberos, specify the local computer name as the remote destination. Also verify that
the client computer and the destination computer are joined to a domain. To use Basic, specify the local computer name
as the remote destination, specify Basic authentication and provide user name and password. Possible authentication
mechanisms reported by server: For more information, see the about_Remote_Troubleshooting Help topic.

I've restarted the WInRM service ad verified configuration of the virtual directories as well. 

Any guidance appreciated!
